Routinely powering up the Symmetrix DMX-3
CAUTION
!
The Symmetrix DMX-3 contains no user-serviceable parts.
Therefore, the system bay and storage bays should not be opened
for any reason by untrained personnel. If the Symmetrix DMX-3 is
in need of repair, only qualified personnel familiar with safety
procedures for electrical equipment and the Symmetrix DMX-3
should access components inside the unit.
Note: For Symmetrix DMX-3 power connection and configuration
requirements, refer to the EMC Symmetrix DMX-3 Physical Planning Guide and
the EMC Symmetrix DMX-3 and DMX-4 Best Practices Guide for AC Power
Connections. Do not use the following procedures for powering up the
Symmetrix DMX-3 for the first time. If you have powered down the
Symmetrix DMX-3 for an emergency condition, call the EMC Service Support
Center for assistance before powering up the system.
Perform these steps to power up the Symmetrix DMX-3 system after
it has been routinely powered down by the PDP power switches:
1. On the rear door of each Symmetrix DMX-3 storage bay Figure 68
on page 280, press the Zone A and Zone B power distribution
panel (PDP) power switches to the up (|) ON position.
2. On the rear door of the Symmetrix DMX-3 system bay Figure 68
on page 280, press the Zone A and Zone B PDP power switches to
the up (|) ON position.
The Symmetrix system begins its initial microcode program load
(IMPL) startup procedure.
3. Wait at least 30 minutes for the IMPL procedure to complete.
Note: The actual IMPL procedure time varies by system type and
configuration.
