Installing Your Switch

Step 5 After the power source is tuned on, set the power button on the front of the power supply
module to the ON position (marked “— ').
Step 6 Check the LEDs on the power supply module as the switch is powered on to verify that
the -48V/+24V LED indicating external power status is on, and that the +12V LED
indicating internal power conversion is on. If not, recheck the power supply and power
cable connections at the supply source and at power supply module.
Step 7 If you have installed both a primary and redundant power supply module, verify that the
LEDs on both modules are lit as indicated in the preceding step.
Connecting to the Console Port
The RJ-45 serial port on the front panel is used to connect to the switch for out-of-band console
configuration. The on-board configuration program can be accessed from a terminal or a PC
running a terminal emulation program.
The pin assignments used to connect to the serial port are provided in Table 12.
WARNING:
If the power leads are plugged into the wrong holes, the power supply will not work properly and
may damage the switch.
