Handle a power supply/system cooling (power/cooling) module
gently and use an ESD wristband. Do not remove a power/cooling
module until you have a replacement module available.
Access to the disks in your enclosure will time out and the disks
will spin down two minutes after a power/cooling module is
removed from the enclosure. While the system can continue
operating on a single power supply, the loss of a module’s two
blowers will cause a time-out unless you replace the module within
two minutes.
When replacing a power/cooling module, make certain the green
LED on one module has been steadily on for at least 5 seconds
before removing power from the second module.
Follow these steps to replace a power/cooling module.
1. Unplug the AC line cord as shown in Figure 3-15.
Figure 3-15 Unplugging the AC power cord
2. Turn the captive screw counterclockwise to release the module,
and then remove the power/cooling module as shown in
Figure 3-16.
