Note You can get replacement power and relay connectors (PWR-2955-CONNECT=)

by calling Cisco Technical Support. See the “Obtaining Technical Assistance”

section on page xxx.

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 “Cable and Adapter

Specifications” section on page B-5.

Warning

If you connect or disconnect the console cable with power applied to the

switch or any device on the network, an electrical arc can occur. This could

cause an explosion in hazardous location installations. Be sure that power is

removed or the area is nonhazardous before proceeding.

To verify switch operation, perform POST on the switch in a nonhazardous

location before installation.

Statement 1065

LEDs

You can use the LEDs to monitor switch activity and performance. The LEDs on

all Catalyst 2955 switches are on the bottom edge of the front panel. The LEDs

are visible in both face-up and parallel mounting configurations, as shown in

Figure 2-7 and Figure 2-8.

Note The 10/100 port status LEDs show port status only.

All LEDs are visible through the GUI management applications—the 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.
