Switch Ports

Uplink Ports

This section describes the uplink ports on Cisco Catalyst IE3100 Rugged Series Switches. The ports vary depending on the switch model.

1000BASE-T/1000BASE-X Dual-Media Ports

Dual-media ports include SFP and copper uplink ports. The SFP ports support 1-Gb and 100-Mb modules. The copper ports support 1000BASE-T, 100BASE-TX, and 10BASE-T, with autonegotiation, auto-MDIX, and cable diagnostics on an RJ-45 connector.

By default, the SFP interface has the higher priority if both the RJ-45 and the SFP interfaces are active. You can override the default priority with the CLI command media-type SFP | RJ45 .

IE-3100-8T2C-E, IE-3100-18T2C-E, IE-3105-8T2C-E, and IE-3105-18T2C-E switches support dual-media ports.

Gigabit Ethernet SFP Only Ports

Gigabit SFP uplink ports support 1-Gb SFP and 100-Mb SFP modules. SFPs installed in these ports can draw up to 825mW each.

IE-3100-4T2S-E is the only switch model that has gigabit SFP only ports.


Note

Downlink Ports

All Cisco Catalyst IE3100 Rugged Series Switches have gigabit 1000BASE-T ports that support 1000BASE-T, 100BASE-TX, and 10BASE-T with autonegotiation, auto-MDIX, and cable diagnostics on an RJ-45 connector.

The number of downlink ports varies depending on the switch model. See Cisco Catalyst IE3100 Rugged Series Swtiches for more information.

Port Status LEDs

Each Ethernet port has a port LED that displays information about the individual port. The dual-media ports have two LEDs, one by the SFP connector and the second by the RJ-45 connector.

Table 1. Port Status LED States

LED State

Port Status

Off

No link, or the port is administratively shut down.

Green

Link present, but no activity.

Blinking green

Activity: Port is sending or receiving data.

Alternating green and amber

Link fault. Error frames can affect connectivity, and errors such as excessive collisions, CRC errors, and alignment and jabber errors are monitored for a link-fault indication.

Amber

Port is blocked by Spanning Tree Protocol (STP) and is not forwarding data.

After a port is reconfigured, the port LED can remain amber for up to 30 seconds as STP checks the switch for possible loops.

Management Ports

You can connect the switch to a computer running Microsoft Windows or to a terminal server through either of the two console ports on the front panel. One is an RS-232 port with an RJ-45 connector and the other is a USB micro-Type B port. The USB port is behind a door that also covers the SD card slot.

The RS-232 console port uses an RJ-45-to-DB9 female cable. The USB console port uses a USB Type B-to-5-pin micro-Type B cable. The USB-micro console interface speeds are the same as the RJ-45 console interface speeds.

By default, the USB console is the active input whenever the USB console is connected, and the RJ-45 console is active when the USB console is not plugged in.

To use the USB-micro console port, you must install the Cisco Windows USB device driver on the device that is connected to the USB-micro console port and that is running Microsoft Windows.

With the Cisco Windows USB device driver, connecting and disconnecting the USB cable from the console port does not affect Windows HyperTerminal operations. Mac OS X or Linux requires no special drivers.

Management Port LED

The two management ports share a console LED, which shows which console port is in use. If both RS-232 and USB ports are connected, the USB port has priority, unless you have disabled the USB console.

Table 2. Management Port LED States

LED State

Port Status

Off

The USB port is not active; the RJ-45 port is active.

Green

The RJ-45 port is active; the USB port is not active.

Power Connectors

Each Cisco Catalyst IE3100 Rugged Series Switch supports 9.6–60V DC DIN rail power inputs, which provide active-standby redundancy. The input with the higher voltage supplies all the power to the switch.

You connect power to the switch through the front panel connectors. The switch has a dual-feed DC power supply: Two connectors provide primary and secondary DC power (DC-A and DC-B). Each input has an independent screw terminal and an LED status indicator.

The DC power connectors are near the top right of the front panel. The power connector labeling is on the panel. The positive DC power connection is labeled “+”, and the return connection is labeled “–”.

Figure 3. Power Connector
Power connector

The switch can operate with a single power source or with dual power sources. When both power sources are working, the switch draws power from the DC source with the higher voltage. If one of the two power sources fail, the other continues to power the switch.

In systems configured with the redundant power option, connect each of the two power supplies to separate independent power sources. If you fail to do this, your system might be susceptible to total power failure due to a fault in the external wiring or a tripped circuit breaker.

The following table shows the power connector LED states and what they mean.

Table 3. Power Connector LED States

Alarms

You connect the alarm signals to the Cisco Catalyst IE3100 Rugged Series Switch through the alarm connector. The switch has two dry-contact alarm inputs and one dry-contact Form-C relay alarm output.

The alarm connector attached to the bottom right of the front panel with provided captive screws. It provides six alarm wire connections.

Figure 4. Alarm Connector
Alarm connector
The alarm inputs are electrically isolated from system ground to prevent ground loops, but the inputs are not isolated from each other. The alarm output is isolated from system ground and from the alarm inputs. The alarm output supports signal levels of up to 48 VDC.

Both alarm input circuits can sense if the alarm input is open or closed. The alarm inputs can be activated for environmental, power supply, and port status alarm conditions. From the CLI, you can configure each alarm input as an open or closed contact.

The alarm output circuit is a relay with a normally open and a normally closed contact. The switch is configured to detect faults that are used to energize the relay coil and change the state on both of the relay contacts: normally open contacts close, and normally closed contacts open. The alarm output relay can be used to control an external alarm device, such as a bell or a light.

There is a separate LED for each of the two inputs and for the output.

Express Setup Button

Express Setup is a web-based procedure to configure initial IP address information to the new switch. It provides a simple way to manage the switch and connect it to an existing network of local routers and the internet.

The Cisco Catalyst IE3100 Rugged Series Switch front panel has an Express Setup button and a setup LED. The button is recessed to prevent accidental activation; you need a paper clip or similar object to press it. You trigger different Express Setup features by varying the amount of time that you press the button.

Table 6. Express Setup Modes

Mode

Seconds Required to Trigger Mode

Description

Short Press

1 to 5

Places the switch into Express Setup mode.

Medium Press

SD Card Connector

The switch supports an SD card that makes it possible to replace a failed switch without configuring the replacement switch. You can also use the SD card to copy files on and off the system.

The connector is on the front of the switch, behind a cover that protects the SD card and holds it in place. The cover also protects the USB console port.

Rear Panel

The rear panel of the switch has a latch for installation on a DIN rail. The latch is spring-loaded to move down to position the switch over a DIN rail and return to the original position to secure the switch to a DIN rail.
