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.
