Servicing a DAE2
Replacing a Power Supply/System Cooling Module
CAUTION
!
Handle a power supply/system cooling module gently and use an
ESD wristband. Do not remove a power/cooling module until you
have a replacement module available.
If one power supply is off and the other is on, do not turn one on
and immediately turn off the other. Instead, turn one on and wait
five seconds after the green LED lights before turning the other off.
Turn off the power supply before unplugging the power cord from
the supply.
Access to the disks in your enclosure will time out and the disks will
power down two minutes after a power supply/system cooling
module is removed from the system. 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.
Follow these steps to replace a power supply/system cooling
module.
1. Turn off the power supply and unplug its ac line cord as shown
Figure 3-15.
