Removing and Replacing Enclosure Components
5
Immediately replace the APC to maintain correct airflow and
cooling. Failed APCs must be replaced within five minutes, or
the system does an orderly shut-down.
Caution:
The enclosure will overheat without adequate
cooling and airflow, which could cause damage to disk
drives and other components.
Installing an APC
Warning:
To avoid electrical shock,
do not
insert any
instruments or tools into the open APC slot.
To install an APC into the Storage Enclosure:
1
Ensure that the handles of the new APC module are lowered
(open).
Note:
Do not
use the handles to lift or carry the APC
modules.
2
Holding the APC module with the handles towards you, slide it
into the empty slot.
3
Gently push up on both handles
simultaneously to fix the APC
module into place (shown at right).
4
Secure the APC module by hand-
tightening the screws.
Do not
over-
tighten them.
5
Reconnect the power cable to the APC module’s power
connector.
6
Power on the APC module.
When their local power supply is detected, the fans return to
their normal speed.
