Power-Off procedure
A 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.
2. Turn on both power switches at the rear of the unit. The unit
powers on and performs power-on self-tests (POSTs).
NOTE: If two power cords are used for high availability, plug the cords
into separate facility power circuits.
3. During POSTs:
a. The green power (PWR) LED on the switch front panel
illuminates.
b. The amber system error (ERR) LED on the switch front panel
blinks momentarily while the switch is tested.
c. The green LEDs associated with the Ethernet port blink
momentarily while the port is tested.
d. The green and amber LEDs associated with the ports blink
momentarily while the ports are tested.
4. After successful POST completion, the green power (PWR) LED
remains illuminated and all other LEDs extinguish.
5. If a POST error or other malfunction occurs, go to
MAP
on page -183 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.
To power off the switch:
1. Notify the customer the switch is to be powered off. Ensure the
customer's system administrator quiesces Fibre Channel frame
traffic through the switch and sets attached devices offline.
2. Set the switch offline
(Set offline state
on page -335).
