154 Edge Switch 2/24 Service Manual

Power-On Procedure

To power-on the switch:

1. One alternating current (AC) power cord is required for each power supply.

Ensure power cord(s) are available to connect the switch to facility power.

WARNING: A Hewlett-Packard-supplied power cord is provided for each

switch power supply. To prevent electric shock when connecting the switch to

primary facility power, use only the supplied power cord(s), and ensure the

facility power receptacle is the correct type, supplies the required voltage,

and is properly grounded.

Note: Turn on both power switches at the rear of the unit. The unit powers on and

performs power-on self-tests (POSTs). If two power cords are used for high

availability, plug the cords into separate facility power circuits.

2. During POSTs:

— The green power (PWR) LED on the switch front panel illuminates.

— The amber system error (ERR) LED on the switch front panel blinks

momentarily while the switch is tested.

— The green LEDs associated with the Ethernet port blink momentarily

while the port is tested.

— The green and amber LEDs associated with the ports blink momentarily

while the ports are tested.

1. After successful POST completion, the green power (PWR) LED remains

illuminated and all amber LEDs extinguish.

2. If a POST error or other malfunction occurs, go to “MAP 0000: Start MAP”

on page 29 to isolate the problem.

Note: When powering on the switch after removing and replacing a faulty FRU, the

amber system error LED may remain illuminated. Clear the system error LED as part of

the replacement procedure.
