Additional Service information
Powering on the Controller
Note
All drive modules must be powered on before you
power-on the Controller.
The controller might take from three to 10 seconds to
power-up. During this time, the amber and green LEDs on
the controller unit will flash.
After power-on, check all fault LEDs to make sure they are
off. If a fault LED is on, refer to the “Symptom-to-FRU
Index” on page 47.
Recovering from a Power Supply
Shutdown
Both power supplies have a built-in temperature sensor
designed to prevent the power supplies from overheating.
If a temperature sensor detects an over-temperature
condition, ambient air temperature of 70° C (158° F) or
above, the "overheated" power supply will automatically
shut down. The other power supply remains on as long as
its temperature remains below 70° C (158° F). If not, the
second power supply will shut down, which turns off all
power to the controller unit.
Once the air temperature cools to below 70° C (158° F),
the power supplies automatically restart. An automatic
restart resets the controllers, attempts to spin up the drives
(which has no effect on the drives if they are already
running), and returns the controller unit to a normal
operating state. Typically, you will not need to perform
recovery procedures after an automatic power supply
shutdown and restart.
After a power supply shutdown, check all controller LEDs.
If the power supply power LED is off, or the amber power
supply LED on the front cover is on, go to
“Symptom-to-FRU Index” on page 47.
Connectors and Host IDs
The host ID switches and connectors for interface cables
are on the connector plate located on the back of the
controller unit.
Host and Drive ID Numbers
Each controller must have a unique Fibre Host ID number.
The host ID numbers assigned to each controller are
based on two elements:
Host ID numbers set through hardware switches on
the controller unit. There are five Host ID switches
