Turning the Expansion Unit On and Off
3. Turn on both power-supply switches on the back of the
expansion unit.
Note: The expansion unit may 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 power up sequence is complete,
only the green LEDs should remain on. If you still have
one or more amber LEDs on, refer to Table 2 on page 60.
If you are restarting the system after a normal shutdown, wait at
least 10 seconds before you attempt to turn on both power-supply
switches.
