Verifying Switch Operation

If you want to connect a terminal to the switch console port, 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.

Verifying Switch Operation

Before installing the switch in a rack, on a wall, or on a table or shelf, you should power on the switch
and verify that the switch passes POST. See Section 3, "Running Express Setup," in the getting started
guide for the steps required to connect a PC to the switch console port and to power on the switch.
While the switch powers on, it automatically begins POST, a series of tests that verifies that the switch
functions properly. When the switch begins POST, the system LED is off. POST has completed
successfully when the SYST and STAT LEDs are green.
If a switch fails POST, the System LED turns amber. If POST fails, see
to determine a course of action.
Note POST failures are usually fatal. Call Cisco Systems if your switch does not pass POST.
After a successful POST, follow these steps:
Turn off power to the switch.
Step 1
Disconnect the cables.
Step 2
Determine where you want to install the switch.
