Power On the Switch

Caution Remove the protective liner before applying power to the switch.

Failure to remove the protective liner could result in thermal damage to the

switch.

Locate the circuit breaker on the panel board that services the DC circuit, and

switch the circuit breaker to the ON position.

Running POST

After the power is connected, the switch automatically begins POST, a series of

tests that verifies that the switch functions properly.

Note The uplink port status LEDs provide system and status information during POST.

On the Catalyst 2955C-12 and 2955S-12, the uplink ports are labeled 13 and 14.

On the Catalyst 2955T-12, the uplink ports are labeled 1 and 2.

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.
