Netfinity EXP15 - Performing a shutdown and turning the power on

Applicable to: World-Wide

Source: Hardware Maintenance Manual

Performing a Shutdown

Note If the Expansion Unit loses power unexpectedly, it might be due to a hardware failure in the power system or mid-plane (see "Symptom-to-FRU Index").

To perform a shutdown:
1. Make sure that all I/O activity has stopped. If applicable, logically disconnect from the host controller.
2. Make sure that all amber Fault LEDs are off. If any Fault LEDs are lit (drives, power supplies, or fans), correct the problem before you turn off the power.
3. Turn off both power supply switches on the back of the Expansion Unit.

Turning the Power On
Use this procedure to power-on the Netfinity EXP15 Storage Expansion unit.

Initial start-up:
1. Verify that all communication and power cables are plugged into the back of the Expansion Unit.

a. All hard disk drives are locked securely in place.
b. The Option ID switch on the Expansion Unit is set correctly.
c. The host controller and other SCSI bus devices are ready for the initial power-up.
d. Power-on the Expansion Unit before powering on the server.

2. Turn on the power to each device, based on this power-up sequence.
3. Turn on both power supply switches on the back of the Expansion Unit.
4. Only the green LEDs on the front and back should be on. If one or more of the amber Fault LEDs are on, refer to "Symptom-to-FRU Index".

Re-starting:
If you are re-starting after a normal shutdown, wait at least ten seconds before you attempt to turn on either power supply switch.
