Maintenance
WARNING:
To reduce the risk of injury from electric shock, remove the power
cord before servicing.
When the CMC indicates that the batteries in the door lock control unit
require changing, remove the screws
1
, lift the cover
2
off, and replace
the six batteries with the same type and capacity (NiMH, size AA,
1100mAh)
3
.
CAUTION:
There is a risk of explosion if battery is replaced by an incorrect type.
Dispose of used batteries properly.
If the fuse
2
has opened, be sure that the condition that caused the fault
has been cleared. Remove the fuse cover
1
. Replace the fuse
2
with the
exact rating as specified on the unit label. The second fuse
3
is a spare.
Contact your Compaq authorized service representative for more details.
Repairs to the CMC door lock control unit and lock mechanism must be
carried out by Compaq or a Compaq authorized service representative.
Configuring the Software
Configure the door lock control unit using the Compaq Intelligent
Rack Manager Lite software (see the
Compaq Console Manage-
ment Controller User Guide
). One CMC is able to support up to
two door lock kits.
DOORS AND SENSORS:
For each door lock kit, select the doors that must be closed before
the lock should activate. Intrusion sensors must monitor these
selected doors. From the Accessory Setup screen of the Compaq
Intelligent Rack Manager Lite software, select at least one door
for each lock kit.
Each door lock control unit locks and unlocks, as a pair, the front
door and the rear door of a single rack. For a secure rack, the
system should verify that the front and rear doors are closed
before the lock activates. The intrusion sensors indicate to the
system that the doors are closed and are ready to be locked.
PRESETS:
From the
Accessory Setup
screen, preset the lock response to
four fault conditions:
■
Power Failure
■
Low Battery
■
Network Failure
■
Communication Failure
If any of these faults occur, the door lock control unit responds by
keeping the doors locked, or by immediately unlocking the doors,
or by enabling the
Concealed Door Release
button, as selected in
the software.
SETUP EXAMPLE:
Power Failure
No
Low Battery
Yes
Network Failure
Enable Concealed Door Release
Communication Failure
Enable Concealed Door Release
The rack remains locked if the door lock control unit loses AC
power. The door lock control unit continues to operate using the
backup battery power.
NOTE:
If the CMC also loses AC power, you will not be able to change any settings.
If the AC power is not restored within approximately six hours,
the Low Battery alert is triggered and the doors unlock. This alert
ensures that sufficient battery power is reserved to unlock the
doors. After 30 minutes, the door lock control unit stops function-
ing. When the AC power is restored, the door lock control unit
automatically relocks all the doors and begins recharging the
batteries.
If the CMC detects a network failure, the doors can be opened by
pressing the
Concealed Door Release
button. The CMC deter-
mines a Network Failure has occurred if the CMC fails to
communicate with the Compaq Intelligent Rack Manager Lite
software for approximately four minutes.
NOTE:
If you are using management software other than Compaq Intelligent Rack
Manager Lite, ensure that the
Network Failure
condition is selected as
No
.
If the Compaq Intelligent Rack Manager Lite service is not running on the
management console, the CMC detects a Network Failure and responds
accordingly.
If the CMC loses communication with the door lock control unit,
a communication failure will be triggered. The doors can then be
opened by pressing the
Concealed Door Release
button.
Connecting to an Additional Rack
A single CMC can support up to two door lock kits. Repeat steps
1 through 7 to complete installation of the door lock equipment for the
second rack. Connect the second I
2
C cable
2
between the two door lock
control units. Connect the cable from the lock port to the open CMC lock
port
1
. Set the switch on the door lock control unit to match the lock port
used on the CMC. Connect the second concealed door release cable and
the AC power cable as detailed in steps 9 and 10.
