Turning the expansion unit on and off
This section contains instructions for turning the expansion
unit on and off under normal and emergency
circumstances.
If you are turning on the expansion unit after an
emergency shutdown or power outage, refer to “Restoring
power after an emergency” on page 68.
Turning on the expansion unit:
Use this
procedure to turn on the power for the initial startup of the
expansion unit.
1. Verify that:
a. All communication and power cables are plugged
into the back of the expansion unit and an ac
power outlet.
b. All hard disk drives are locked securely in place.
c. The tray number switches on the expansion unit
are set correctly. (See “Setting the interface
options” on page 76 for more information.)
2. Check the system documentation for all the hardware
devices you intend to turn on and determine the
proper startup sequence.
Note
Be sure to turn on the IBM Netfinity EXP500
before or at the same time as the server.
3. Turn on the power to each device, based on the
startup sequence.
Attention:
If you are restarting the system after a normal
shutdown, wait at least 10 seconds before you turn
on the power supply switches.
4. Turn on both power supply switches on the back of
the unit.
The expansion unit might take a few seconds to
power up. During this time, you might see the amber
and green LEDs on the expansion unit turn on and off
intermittently. When the startup sequence is
complete, only the green LEDs on the front and back
and the amber Bypass LEDs for unconnected GBIC
