A.4 Powering Up After an Emergency Shutdown
CAUTION:
This unit contains no user-serviceable parts, so it should not be opened for
any reason by untrained personnel. If the CDA 7 is in need of repair, only
qualified personnel familiar with safety procedures for electrical equipment
and the CDA 7 should access components inside the unit.
When the CDA 7 is powered down via the red EPO switch, a breaker switch on the
power subsystem trips.
Perform these steps to power on the CDA 7 after it has been powered off by the red
EPO switch.
CAUTION:
Always contact the Bull Customer Support Center prior to powering up the
CDA 7 after an emergency shutdown.
1. Make sure all operator panel switches (channel director and disk director) are
in the disable position.
2. Lift the EPO switch on the rear door to the up (|) position.
3. Lift the AC power switch on the rear door to the up (|) position.
NOTE:
The CDA 7 begins its IML procedure. This procedure takes several minutes to
perform.
4. When the IML procedure completes, all directors show "0F" in their LED
displays.
CAUTION:
Before you enable channel and disk directors from the CDA 7 operator
panel, contact an EMC Product Support Engineer from the EMC
Customer Support Center. Explain that an emergency shutdown was
performed and that you need them to check the condition of the CDA 7
before you enable the channel and disk directors. When the CDA 7 checks
out correctly, proceed to the next step.
5. Place the operator panel switches (channel director and disk director) in their
enable position.
When "0F" clears from all director LED displays, the CDA 7 is then available
to the host system(s).
