EonStor DS S12/S16/S24 Series Hardware Manual
5.4.2
Replacing the PSU on S12x-Rxxxx Models and S16 RAID Systems
The failed PSU should be replaced as soon as possible, but only when you have a
replacement module in your hand. Contact technical support for more details. (See
6.4 Contact Information
for details)
WARNING
Although the system can operate using a single PSU module, it is not advisable to run
the EonStor DS system with a single PSU module for an extended period of time.
Do not use a PSU or cooling module from EonStor DS ASIC400 series. They look
similar but they may come with cooling fans with different rotation speeds, and may
not be sufficient for your ASIC667 models.
To replace a PSU, follow these steps:
1.
Power off the PSU
. The power switch is located on each PSU’s rear panel.

2.
Disconnect the power cord.
3.
Loosen the retention screw
that secures the extraction handle to the chassis.

4.
Remove the PSU module.
Grab the extraction handle and pull the handle
upwards to disconnect the PSU from the backplane connectors. Once dislodged,
gently pull the PSU out of the subsystem. If the system is mounted in a rackmount
rack, use another hand to support its weight while removing the module.
