Powerup and powerdown sequence
A DAE-AX does not have a power switch. It powers up immediately once it
is connected to a live power source.
Powering up the storage system
1. Verify the following:
Master switch/circuit breakers for any cabinet/rack power strip
are off.
The power cord for power/cooling module A in the DPE-AX
(viewed from the rear, A is the right side of the enclosure) is
plugged into the SPS, if present, and the power cord retention
bails are in place. In a storage system without an SPS, the power
cord for power/cooling module A is plugged directly into a
power source.
The power cord for power/cooling module B is plugged into the
nearest power distribution unit on a different circuit feed than
the SPS or module A. In systems with two SPSs, power/cooling
module B is plugged into its corresponding SPS.
In a dual-SP system, the serial connection (sense cable) between
SP A and SPS A is in place. If the system has two SPSs, the serial
cable between SP B and SPS B is in place.
The power cords for the SPSs and any DAE-AXs are plugged
in; the power cords for the A and B sides do not share a power
source; and, the power cord retention bails are in place.
Any other devices in the cabinet are correctly installed and
ready for powerup.
Figure 9 shows a storage system with one SPS correctly cabled for
high availability.
