Environmental Monitoring and PoE Management

The Cisco 4000 series Integrated Services routers have hardware and software features that periodically monitor the router's environment. For more information, see the Hardware Installation Guide for the Cisco 4000 Series Integrated Services Routers.

This chapter provides information on the environmental monitoring features on your router that allow you to monitor critical events and generate statistical reports on the status of various router components and, includes the following sections:

Environmental Monitoring

The router provides a robust environment-monitoring system with several sensors that monitor the system temperatures. Microprocessors generate interrupts to the HOST CPU for critical events and generate a periodic status and statistics report. The following are some of the key functions of the environmental monitoring system:

  • Monitoring temperature of CPUs, motherboard, and midplane

  • Monitoring fan speed

  • Recording abnormal events and generating notifications

  • Monitoring Simple Network Management Protocol (SNMP) traps

  • Generating and collecting Onboard Failure Logging (OBFL) data

  • Sending call home event notifications

  • Logging system error messages

  • Displaying present settings and status

Environmental Monitoring and Reporting Functions

Monitoring and reporting functions allow you to maintain normal system operation by identifying and resolving adverse conditions prior to loss of operation.

Environmental Monitoring Functions

Environmental monitoring functions use sensors to monitor the temperature of the cooling air as it moves through the chassis.

The local power supplies provide the ability to monitor:

  • Input and output current

  • Output voltage

  • Input and output power

  • Temperature

  • Fan speed

The router is expected to meet the following environmental operating conditions:

  • Operating Temperature Nominal—32°F to 104°F (0°C to 40°C)

  • Operating Humidity Nominal—10% to 85% RH noncondensing

  • Operating Humidity Short Term—10% to 85% RH noncondensing

  • Operating Altitude—Sea level 0 ft to 10,000 ft (0 to 3000 m)

  • AC Input Range—85 to 264 VAC

In addition, each power supply monitors its internal temperature and voltage. A power supply is either within tolerance (normal) or out of tolerance (critical). If an internal power supply's temperature or voltage reaches a critical level, the power supply shuts down without any interaction with the system processor.

The following table displays the levels of status conditions used by the environmental monitoring system.

Table 1. Levels of Status Conditions Used by the Environmental Monitoring System

Status Level

Description

Normal

All monitored parameters are within normal tolerance.

Warning

The system has exceeded a specified threshold. The system continues to operate, but operator action is recommended to bring the system back to a normal state.

Critical

An out-of-tolerance temperature or voltage condition exists. Although the system continues to operate, it is approaching shutdown. Immediate operator action is required.

The environmental monitoring system sends system messages to the console, for example, when the conditions described here are met:

Fan Failure

When the system power is on, all the fans should be operational. Although the system continues to operate if a fan fails, the system displays the following message: 

%IOSXE_PEM-3-FANFAIL: The fan in slot 2/0 is encountering a failure condition

Sensors Out of Range

When sensors are out of range, the system displays the following message: 

%ENVIRONMENTAL-1-ALERT: V: 1.0v PCH, Location: R0, State: Warning, Reading: 1102 mV
 
%ENVIRONMENTAL-1-ALERT: V: PEM Out, Location: P1, State: Warning, Reading: 0 mV
 
%ENVIRONMENTAL-1-ALERT: Temp: Temp 3, Location R0, State : Warning, Reading : 90C

Fan Tray (Slot P2) Removed

When the fan tray for slot P2 is removed, the system displays the following message: 

%IOSXE_PEM-6-REMPEM_FM: PEM/FM slot P2 removed

Fan Tray (Slot P2) Reinserted

When the fan tray for slot P2 is reinserted, the system displays the following message: 

%IOSXE_PEM-6-INSPEM_FM: PEM/FM slot P2 inserted

Fan Tray (Slot 2) is Working Properly

When the fan tray for slot 2 is functioning properly, the system displays the following message: 

%IOSXE_PEM-6-PEMOK: The PEM in slot P2 is functioning properly

Fan 0 in Slot 2 (Fan Tray) is Not Working

When Fan 0 in the fan tray of slot 2 is not functioning properly, the system displays the following message: 

%IOSXE_PEM-3-FANFAIL: The fan in slot 2/0 is encountering a failure condition

Fan 0 in Slot 2 (Fan Tray) is Working Properly

When Fan 0 in the fan tray of slot 2 is functioning properly, the system displays the following message: 

%IOSXE_PEM-6-FANOK: The fan in slot 2/0 is functioning properly

Main Power Supply in Slot 1 is Powered Off

When the main power supply in slot 1 is powered off, the system displays the following message: 

%IOSXE_PEM-3-PEMFAIL: The PEM in slot 1 is switched off or encountering a 
failure condition.

Main Power Supply is Inserted in Slot 1

When the main power supply is inserted in slot 1, the system displays the following messages: 

%IOSXE_PEM-6-INSPEM_FM: PEM/FM slot P1 inserted
%IOSXE_PEM-6-PEMOK: The PEM in slot 1 is functioning properly

Temperature and Voltage Exceed Max/Min Thresholds

The following example shows the warning messages indicating the maximum and minimum thresholds of the temperature or voltage: 

Warnings :
--------
For all the temperature sensors (name starting with “Temp:”) above,
the critical warning threshold is 100C (100C and higher)
the warning threshold is 80C (range from 80C to 99C)
the low warning threshold is 1C (range from -inf to 1C).
 
For all voltage sensors (names starting with "V:"),
the high warning threshold starts at that voltage +10%. (voltage + 10% is warning)
the low warning threshold starts at the voltage -10%. (voltage - 10% is warning)

Environmental Reporting Functions

You can retrieve and display environmental status reports using the following commands:

  • debug environment

  • debug platform software cman env monitor polling

  • debug ilpower

  • debug power [inline | main]

  • show diag all eeprom

  • show diag slot R0 eeprom detail

  • show environment

  • show environment all

  • show inventory

  • show platform all

  • show platform diag

  • show platform software status control-processor

  • show version

  • show power

  • show power inline

These commands show the current values of parameters such as temperature and voltage.

The environmental monitoring system updates the values of these parameters every 60 seconds. Brief examples of these commands are shown below:

Configuring Power Supply Mode

You can configure the power supplies of both the router and a connected Power over Ethernet (PoE) module.

Configuring the Router Power Supply Mode

Configure the main power supply on the router using the power main redundant command:

  • power main redundant—Sets the main power supply in redundant mode.

  • no power main redundant—Sets the main power supply in boost mode.


Note

The default mode for the router power supply is redundant mode.

Configuring the External PoE Service Module Power Supply Mode

Configure the power supply of an external PoE service module using the power inline redundant command:

  • power inline redundant—Sets the external PoE service module power supply in redundant mode.

  • no power inline redundant—Sets the external PoE service module power supply in boost mode.


Note

The default mode for the external PoE service module power supply is redundant mode.

The show power command shows whether boost or redundant mode is configured and whether this mode is currently running on the system.

Examples for Configuring Power Supply Mode

Example—Configured Mode of Boost for Main PSU and PoE Module

In this example, the show power command shows the configured mode as Boost, which is also the current runtime state. The Main PSU shows information about the main power supply. The POE Module shows information about the inline/PoE power. In this example, the current run-time state for the main power supply is the same as the configured state (Boost mode). 

Router# show power
Main PSU :
Configured Mode : Boost
Current runtime state same : Yes
Total power available : 2000 Watts
POE Module :
Configured Mode : Boost
Current runtime state same : Yes
Total power available : 1000 Watts
Router#

Example—Configured Mode of Boost for Main PSU and PoE Module

In this example, the show power command shows the power supplies that are present in the device. The Main PSU and POE Module are configured to the Boost mode, which differs from the current runtime state. The current runtime state is the Redundant mode. A likely explanation for this is that there is only one main power supply present in the router. See mode example 4 in the table titled "Modes of Operation" in Available PoE Power.

You can enter the show platform command to show the power supplies that are present in the device. 

Router# show power
Main PSU :
Configured Mode : Boost
Current runtime state same : No
Total power available : 1000 Watts
POE Module :
Configured Mode : Boost
Current runtime state same : No
Total power available : 500 Watts
Router#

Example—Configured Mode of Redundant for Main PSU and PoE Module

In this example, the show power command shows the configured mode is Redundant for both the main and inline power. The system has one 450 W and one 100 W power supply. 

Router# show power
Main PSU :
Configured Mode : Redundant
Current runtime state same : Yes
Total power available : 450 Watts
POE Module :
Configured Mode : Redundant
Current runtime state same : No
Total power available : 0 Watts
Router#

Example—Configured Mode of Boost for Main Power

In this example, the main power is configured to be in boost mode by using the no form of the power main redundant command. This sets the main power to boost mode with 1450 W and inline power to redundant mode with 500 W. 

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# no power main redundant
Router(config)#
*Jan 31 03:35:22.284: %PLATFORM_POWER-6-MODEMATCH: Inline power is in Redundant mode
Router(config)#
Router(config)# exit
Router#
*Jan 31 03:36:13.111: %SYS-5-CONFIG_I: Configured from console by console
Router# show power
Main PSU :
Configured Mode : Boost
Current runtime state same : Yes
Total power available : 1450 Watts
POE Module :
Configured Mode : Redundant
Current runtime state same : Yes
Total power available : 500 Watts
Router#

Example—Configured Mode of Boost for PoE Power

In this example, an attempt is made to configure the inline power in boost mode by using the no form of the power inline redundant command. The inline power mode is not changed to boost mode because that would require a total power available in redundant mode of 1000 W. The inline power mode is redundant and is shown by the following values for the PoE Module:

  • Configured Mode : Boost

  • Current runtime state same : No 

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# no power inline redundant
Router(config)#
*Jan 31 03:42:40.947: %PLATFORM_POWER-6-MODEMISMATCH: Inline power not in Boost mode
Router(config)#
Router(config)# exit
Router#
*Jan 31 03:36:13.111: %SYS-5-CONFIG_I: Configured from console by console
Router# show power
Main PSU :
Configured Mode : Boost
Current runtime state same : Yes
Total power available : 1450 Watts
POE Module :
Configured Mode : Boost
Current runtime state same : No
Total power available : 500 Watts
Router#

Available PoE Power

For the PoE feature to be available on the external PoE module, the total power from the power supplies must be 500 W or higher.


Note

To ensure the PoE feature is functional on the external PoE module, verify the availability of PoE power on your router using the show platform and show power commands.

To determine there is enough PoE power for use by an external PoE service module, use the show platform and show power commands to calculate the available PoE power based on the wattage values of the main power supplies and PoE inverters.

Take the values of your main P0 and P1 power supplies to give the Total Power (for main power supplies.) Then take the values of your PoE1 and PoE2 power inverters to calculate the Total PoE Power.

The following table shows example modes of operation, which may be similar to your configuration.

The Total PoE Power value, in the final column of the table needs to be 500 W or higher for the PoE feature to be functional on a connected PoE service module.


Note

Add power inverters to the router before inserting an external PoE module. Otherwise, even if the Total PoE Power is sufficient, the PoE power will not be used by the external PoE module and the module will need to be re-booted for the PoE feature to be functional.

Configuring a power mode of boost or redundant on the main power supplies, or PoE inverters, may affect the value for Total PoE Power.

The following table shows all power values in Watts. The wattage ratings of the main power supplies are shown in columns Main P0 and Main P1. The wattage ratings of the PoE inverters are shown in columns PoE0 and PoE1.

In the table above, for 500 W or higher Total PoE Power to be available, the "Total Power" (of the main power supplies) must be 1000 W or higher.

For 1000 W Total PoE Power (see Mode Example 8 above), there must be two 1000 W main power supplies (in Boost mode) and two PoE inverters (also in Boost mode).


Caution

Care should be taken while removing the power supplies and power inverters (especially in Boost mode of operation). If the total power consumption is higher than can be supported by one power supply alone and in this condition a power supply is removed, the hardware can be damaged. This may then result in the system being unstable or unusable.

Similarly, in the case where there is only one PoE inverter providing PoE power to a service module, and in this condition the PoE inverter is removed, the hardware may be damaged, and may result in the system being unstable or unusable.

Managing PoE

The Power over Ethernet (PoE) feature allows you to manage power on the FPGE ports. By using PoE, you do not need to supply connected PoE-enabled devices with wall power. This eliminates the cost for additional electrical cabling that would otherwise be necessary for connected devices. The router supports PoE (802.3af) and PoE+ (802.3at). PoE provides up to 15.4 W of power, and PoE+ provides up to 30 W of power.

PoE Support for FPGE Ports

A PoE module supports PoE on the front panel gigabit ethernet ports (FPGE) such as gig0/0/0 and gig0/0/1. You can configure the PoE service module for the FPGE using the power inline command, which allows you to turn on or turn off the power to a connected device such as an IEEE phone or device. For more information, see Configuring PoE for FPGE Ports.

Monitoring Your Power Supply

You can monitor the total available power budget on your router using the show power inline [GigabitEthernet detail] command in privileged EXEC mode.

This command allows you to check the availability of sufficient power for the powered device type before it is connected to the router.

Example—Inline power where there is no PoE module

In this example, there is no module present that supports PoE. Power is being supplied to an IP phone and a switch.

Example—Inline power to an external PoE service module

In this example, after the output lines for Gi0/0/0, and Gi0/0/1, there are output lines for the external PoE service module. Cisco IOS XE 3.10 and higher supports an external PoE module. Et1/0/0 indicates the internal port (slot 1/0) for the first PoE service module. Et2/0/0 indicates the internal port (slot 2/0) in a second PoE service module.

Although both slots are capable of drawing 750 W of PoE power, in this device only 500 W of PoE power is available. Slot 2/0 (Et2/0/0) has been allocated 369.6 W of PoE power.

Configuring PoE for FPGE Ports

SUMMARY STEPS

  1. enable
  2. configure terminal
  3. cdp run
  4. interface gigabitethernet slot/subslot/port
  5. cdp enable
  6. power inline {auto { auto [max milli-watts] | never}
  7. exit

DETAILED STEPS

  Command or Action Purpose
Step 1

enable

Example:


Router> enable

Enables privileged EXEC mode.

  • Enter your password if prompted.
Step 2

configure terminal

Example:


Router# configure terminal

Enters global configuration mode.

Step 3

cdp run

Example:


Router(config)# cdp run

Enables Cisco Discovery Protocol (CDP) on your router.

Step 4

interface gigabitethernet slot/subslot/port

Example:


Router(config)# interface gigabitEthernet 0/0/0

Allows to configure PoE on ports 0 and 1.

  • PoE can be configured on ports 0 and 1.
Step 5

cdp enable

Example:


Router(config-if)#  cdp enable

Enables CDP in the interface configuration mode.

Step 6

power inline {auto { auto [max milli-watts] | never}

Example:


Router(config-if)# power inline auto

Allows you to set the power inline options for FPGE ports.

  • auto—The auto keyword automatically detects the power inline devices and supplies power to such devices.

  • max milli-watts—The max keyword sets the maximum power allowed on the interface.

  • never—The never keyword disables the detection and ceases the application of inline power.

Step 7

exit

Example:


Router(config-if)# exit

Exits the interface configuration mode.

Verifying if PoE Is Enabled on FPGE Port

You can verify whether the PoE is enabled on the FPGE port by looking at the external LED for this port. The external LED for the FPGE port is labelled as GE POE. The GE POE emits a green light when the internal PoE module is plugged in and functioning properly. The GE POE LED is yellow when the internal PoE is plugged in but not functioning properly. The GE POE LED is off when there are no PoE modules plugged in. For more information on LEDs, see the Hardware Installation Guide for the Cisco 4000 Series Integrated Services Routers.

You can also detect PoE using the show platform and show diag commands.

For more information, see the following examples.
