switch.
Verifying Switch Operation
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
Before installing the switch on a DIN rail or in a 19-inch rack, you should power
on the switch and verify that the switch passes power-on self-test (POST). These
sections describe the steps required to connect a PC to the switch console port, to
power on the switch, and to observe POST:
Connecting a PC or a Terminal to the Console Port, page 4-14
Powering On the Switch and Running POST, page 4-16
Connecting a PC or a Terminal to the Console Port
To connect a PC to the console port, use the supplied RJ-45-to-DB-9 adapter
cable. To connect a terminal to the 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. For console-port and
adapter-pinout information, see the
“Cable and Adapter Specifications” section
on page B-5 .
