Cisco IE 3000 Switch Hardware Installation Guide
Chapter 1 Overview
Front-Panel Description
Alarm relays often control an external alarm device, such as a bell or a light. To connect an external
alarm device to the relay, you must connect two relay contact wires to complete an electrical circuit. Both
alarm terminals on the power and relay connector are labeled A, and you can connect them without
regard to polarity.
See the switch software configuration guide for instructions on configuring the alarm relays.
For more information about the power and relay connector, see Appendix C, “Cable and Connectors.”
You can get replacement power and relay connectors (PWR-IE3000-CNCT=) by calling Cisco Technical
Support.
Console Port
You can connect a switch to a PC through the console port and the supplied RJ-45-to-DB-9 adapter cable.
If you want to connect a switch to a terminal, you need to provide an RJ-45-to-DB-25 female DTE
adapter. You can order a kit (part number ACS-DSBUASYN=) with that adapter from Cisco Systems.
For console-port and adapter-pinout information, see the “Two Twisted-Pair Cable Pinouts” section on
page C-8.
LEDs
You can use the LEDs to monitor the switch status, activity, and performance. Figure 1-10 to Figure 1-13
show the front panel LEDs, and the following sections describe them.
All LEDs are visible through the GUI management applications—the Cisco Network Assistant
application for multiple switches and the device manager GUI for a single switch. The switch software
configuration guide describes how to use the CLI to configure and to monitor individual switches and
switch clusters.
