Feature Overview

The Cisco uBR10012 router can optionally ship with two AC power entry modules (PEMs) that provide a redundant power supply to the system. One AC PEM can provide sufficient power for a fully configured chassis, so that if one AC PEM fails, the other automatically begins providing power for the entire router, without impacting system operations.

---

Note You should be using Cisco IOS Release 12.2(4)XF1, Cisco IOS Release 12.2(4)BC1a, or a later release when using the AC PEM. If using an earlier release, the show environment command will not correctly identify the AC PEM’s error messages.

---

---

Caution The Cisco uBR10012 router supports using either the AC PEM or the DC PEM, but it does not support mixing AC and DC PEMs. Both PEMs must be either AC PEMs or DC PEMs.

---

The AC PEMs use standard 200–240 VAC (50/60 Hz) input power obtained through power receptacles on the front panel of each PEM. The two AC PEMs convert the AC power to provide filtered, redundant, and load shared DC power to the Cisco uBR10012 chassis.

---

Caution The AC PEMs cannot be used with a 100–120 VAC input power source.

---

---

Tips For fully redundant power protection, use either an uninterruptible power supply (UPS) or a separate AC-input power source for each AC PEM.

---

This document contains the procedures to replace an existing second (redundant) AC PEM and to replace both AC PEMs.

---

Note You do not need to shut down the Cisco uBR10012 router to replace a redundant AC PEM. If you are replacing both AC PEMs, you can replace one, bring it online, and then replace the other one to avoid shutting down the system.

---

---

Caution Although one AC PEM can provide sufficient power for a fully configured Cisco uBR10012 chassis, the system should not be run for an extended period of time with only one AC PEM. If an AC PEM fails, order and install a replacement AC PEM as soon as possible. The product order number for a replacement AC PEM is UBR10-PWR-AC=. For proper airflow, cooling, and safety, do not remove the failed unit until the replacement unit is available for installation.

---

---

Note The output of the show inventory command does not display the serial number for the AC PEM (UBR10-PWR-AC). Visually inspect the serial number label printed on the AC PEM to locate the serial number.

LEDs

Table 1 describes the LEDs on the AC PEM.

 

Table 1 AC PEM LEDs and Their Function

LED	Color	Description
Power	Green	The PEM is on, is receiving power from the AC power source, and is providing power to the Cisco uBR10012 chassis (normal operations).
Fault	Yellow	Indicates that AC-input power is being received by the PEM, but that the PEM is not supplying power to the chassis, typically because the PEM’s power switch is turned to the standby position. If the power switch is in the ON position, the PEM is not operating correctly.

Air Flow

The AC PEM works together with the fan assembly module to ensure that the Cisco uBR10012 chassis is properly cooled during normal operation. Figure 3 shows the airflow through the Cisco uBR10012 chassis when dual AC PEMs are installed.

Figure 3 Airflow Through the Cisco uBR10012 Chassis with Dual AC PEMs

 

---

Note Figure 3 shows the Cisco uBR10012 chassis without the front bezel installed, but the front bezel should be installed during normal operation so that the air filter in the bezel can filter the incoming air before it enters the chassis.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.
• Disconnect all power and external cables before moving a chassis.
• Do not work alone when potentially hazardous conditions exist.
• Never assume that power has been disconnected from a circuit; always check.
• Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
• Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are improperly handled, can result in complete or intermittent failures. The AC PEMs contain a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the cards from ESD, use an antistatic strap each time you handle the modules.

Following are guidelines for preventing ESD damage:

• Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Before removing a card from the chassis, connect the equipment end of the strap to a bare metal, unpainted surface on the chassis or rack-mount.
• Handle components by the carrier edges only; avoid touching the card components or any connector pins.
• When removing a module, place it on an antistatic surface or in a static-shielding bag. If the module will be returned to the factory, immediately place it in a static-shielding bag.
• Avoid contact between the modules and clothing. The wrist strap protects the card from ESD voltages on the body only; ESD voltages on clothing can still cause damage.

---

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.

Removing and Replacing an AC PEM

This section contains information on removing and replacing AC PEM modules in the Cisco uBR10012 chassis.

---

Tip The AC PEM is operating correctly when its Power LED is on (green). When the Fault LED is on (yellow), the AC PEM is receiving AC-input power but is not providing power to the system. Verify that the AC PEM is fully inserted into the power bay and that its captive screws have been tightened. Then flip the power switch on the AC PEM to the standby position, wait several seconds, and then back to the ON position. If the Fault LED does not go off and the Power LED does not come on, replace the AC PEM.

---

Tools and Parts Required

To remove and replace an individual power module, you need the following tools and parts:

• Replacement AC PEM (UBR10-PWR-AC=)
• ESD-preventive wrist strap
• Flat-head screwdriver

Unpacking and Preparing the AC PEM

To unpack the AC PEM, complete the following steps:

---

Step 1 Open the shipping carton by cutting the packing tape along the flaps on the top of the box.

Step 2 Remove the PEM from the packaging and place it on an anti-static surface.

Step 3 Keep the packaging and the carton so that you can use them to return the old unit being replaced to the factory. See the “Obtaining Documentation and Submitting a Service Request” section for more information.

Verifying That the DC Power Connectors Are Not Connected

Each of two power bays in the Cisco uBR10012 chassis is above a DC terminal block that is used to provide power only when you are using the DC PEM modules. Do not use these DC terminal blocks when you are using the AC PEMs.

If you have previously used this Cisco uBR10012 router with DC PEMs, first verify that these DC terminal blocks are not currently connected before proceeding with the installation or replacement of the AC PEMs. Figure 4 shows the location of the two DC terminal blocks and how to recognize the wires that might be connected to the blocks.

Figure 4 Location of DC Power Connectors and DC Power Cables

 

---

Note For more information on these DC terminal blocks, see either the Cisco uBR10012 Universal Broadband Router Hardware Installation Guide or the DC Power Entry Module for the Cisco uBR10012 Universal Broadband Router document, which are available on Cisco.com or the Customer Documentation CD-ROM.

---

Replacing a Redundant AC PEM

Follow this procedure to replace a redundant AC PEM, which is typically needed when the Fault LED is on and the troubleshooting steps in the “Troubleshooting the PEM” section do not correct the problem.

---

Tip If you want to replace both AC PEMs without shutting down the router, repeat this procedure for each AC PEM, one at a time. Do not use this procedure if both AC PEMs have failed; instead, use the procedure in the “Replacing Both AC PEMs” section.

---

---

Step 1 Remove the front cover by lifting it up slightly and then pulling it toward you.

Step 2 Turn off the AC PEM you are replacing by pushing down the power switch to the standby position (Figure 5).

Figure 5 Turning an AC PEM Off

 

---

Caution Do not power off both AC PEMs, or the system shuts down and all data traffic stops. Power off only the AC PEM you are replacing.

---

Step 3 Unplug the AC-input power cable from the power plug on the front panel of the AC PEM. For safety, also unplug the other end of the power cable from the AC-input power source.

---

Tips For true redundant power protection, ensure that you are using a separate AC-input power source for each AC PEM.

---

Step 4 Use the screwdriver to loosen the captive screws on the AC PEM you are removing. Then pull the PEM from the chassis by using the handle on the faceplate (Figure 6). Set the AC PEM aside.

Figure 6 Removing the AC PEM

 

Step 5 Verify that the power switch on the replacement AC PEM is in the standby position (Figure 5).

Step 6 Position the replacement AC PEM in the power bay and push it forward, verifying that it goes all the way in and makes a secure connection with the backplane.

Step 7 Use the screwdriver to tighten the captive screws to secure the unit to the chassis (Figure 7).

Figure 7 Installing the AC PEM

 

Step 8 Plug the AC-input power cable into the power receptacle on the front panel of the AC PEM.

Step 9 Route the power cable up the front of the AC PEM and clip it into the two plastic retaining clips attached to the surface of the PEM. Route the power cable out through the right side, so that it will fit through the notch on the right side of the front bezel cover. (Figure 8)

Figure 8 Routing the AC Power Cables

 

Step 10 Plug the other end of the AC-input power cable into a 200–240 VAC power outlet. For fully redundant operation, each AC PEM should use separate power sources, or you should be using an uninterruptible power supply (UPS).

The Fault LED on the AC PEM should be yellow to indicate that the AC PEM is receiving power from the power source but is not yet supplying power to the Cisco uBR10012 chassis.

Step 11 Push up the power switch on the replacement AC PEM to the ON (|) position (Figure 9).

Figure 9 Setting AC Power Switch to the ON Position

 

Step 12 When you turn on the power switch on the AC PEM, the Fault LED should go off and the Power LED should come on (green).

Step 13 Slide the front bezel cover onto the four corner posts of the chassis and then push down, so that the posts are seated in the grooves above the cover holes. The AC power cables should be routed through the notch on the right side of the cover.

---

 

Replacing Both AC PEMs

Use the following procedure to replace or reinstall both AC PEMs. This procedure is typically needed only when you need to move the chassis or reinstall it in another location.

---

Tip This procedure is rarely needed for normal operations because it requires that you shut down the Cisco uBR10012 router and remove all power to the system. To avoid this, Cisco recommends replacing each AC PEM, one at a time, by following the instructions in the “Replacing a Redundant AC PEM” section.

---

---

Step 1 Remove the front cover.

Step 2 Shut down the system using the following procedure:

a. Notify appropriate personnel that you plan to shut down the system and that the shutdown will result in total loss of service. Appropriate personnel includes the regional alarm or network monitoring center, central office personnel, and key customers.

b. Before you shut down the router, use the copy command to save any configuration changes to NVRAM and, if you wish, to a PCMCIA Flash memory card. See the Cisco uBR10012 Universal Broadband Router Software Configuration Guide for instructions about using the copy command.

c. Turn the power switch on each AC PEM to the standby position (Figure 10).

Figure 10 Turning the AC PEM Off

 

Step 3 Unplug the AC-input power cable from the power plug on the front panel of each AC PEM. For safety, also unplug the other end of the power cable from each AC-input power source.

---

Tips For true redundant power protection, ensure that you are using a separate AC-input power source for each AC PEM.

---

Step 4 Use the screwdriver to loosen the captive screws on each AC PEM. Then pull each AC PEM from the chassis by using the handle on the faceplate (Figure 11). Set the two AC PEMs aside.

Figure 11 Removing the AC PEM

 

Step 5 Verify that the power switch on each replacement AC PEM is in the standby position (Figure 10).

Step 6 Position the first replacement AC PEM in the power bay and push it forward. Verify that it goes all the way in and makes a secure connection with the backplane.

Step 7 Use the screwdriver to tighten the captive screws to secure the unit to the chassis (Figure 12).

Figure 12 Installing the AC PEM

 

Step 8 Position the second replacement AC PEM in the power bay and push it forward. Verify that it goes all the way in and makes a secure connection with the backplane. Tighten the captive screws to secure the unit to the chassis (Figure 12).

---

Caution Although one AC PEM can supply sufficient power for a fully configured chassis, run the Cisco uBR10012 router with two AC PEMs installed, because this provides redundant power support.

---

Step 9 Plug the AC-input power cable into the power receptacle on the front panel of each AC PEM.

Step 10 Route the power cable up the front of the AC PEM and clip it into the two plastic retaining clips attached to the surface of the PEM. Route the power cable out through the right side, so that it fits through the notch on the right side of the front bezel cover. (Figure 13)

Figure 13 Routing the AC Power Cables

 

Step 11 Plug the other end of the AC-input power cable into a 200–240 VAC power outlet. For fully redundant operation, each AC PEM should use separate power sources, or you should be using an uninterruptible power supply (UPS).

The Fault LED on each replacement AC PEM should be yellow to indicate that the AC PEM is receiving power from the power source but is not yet supplying power to the Cisco uBR10012 chassis.

Step 12 Push up the power switch on the replacement AC PEM to the ON (|) position (Figure 14).

Figure 14 Setting AC Power Switch to the ON Position

 

Step 13 When you turn on the power switch on each AC PEM, its Fault LED should go off and the Power LED should come on (green).

Step 14 Slide the front bezel cover onto the four corner posts of the chassis and then push down, so that the posts are seated in the grooves above the cover holes. The AC power cables should be routed through the notch on the right side of the cover.

---

 

Troubleshooting the PEM

Check the following to help isolate a problem with the power subsystem:

• Is the Power LED on each AC PEM on (green)?

– If yes, the PEM is connected to an active 240 VAC AC power source and is supplying power to the chassis.

– If the Power LED is not on, and if no other LEDs are on, verify that the AC power source is providing valid power. If necessary, try connecting the AC PEM to another wall outlet or power supply.

• Is the Fault LED on (yellow)?

– If yes, it indicates that the PEM is connected to an active 240 VAC power source but is not providing power to the chassis. Check that the AC PEM is properly inserted into the chassis and that its power switch is on.

• Check the status of the AC PEM using the show environment command.

---

Note The show environment command provides accurate information on the AC PEM only when using Cisco IOS Release 12.2(4)XF1, 12.2(4)BC1a, or a later release. If using an earlier release, the show environment command will not correctly identify the AC PEM’s error messages.

---

• If none of the above suggestions correct the problem, the AC PEM could be faulty. Contact a service representative for further instructions.
