Maintenance
4 Look at each MCPM and verify that none of the red alarm LEDs are illuminated. Normally, the
green and amber LEDs are illuminated. Refer to Table C-7 on page 208 to interpret the LED
status indicators.
5 Look at the control card(s) and verify that the green and amber LEDs are illuminated on the
active control card, and that the green LED is on for the standby controller (if present). Verify
that the low battery LED is off on one or both control cards. Table C-6 on page 208 describes
the various LEDs and their meaning.
6 Inspect the air intake filter located inside the door. If the filter is dirty or clogged, refer to
Intake
Filter Screen Cleaning
for information on how to clean it.
Next, inspect the rear of the matrix frame.
1 Verify that there are no missing backplane cover plates. Cover plates are required to ensure
proper cooling in the frame.
2 Place your hand near the air exhausts. You should feel strong air pressure evenly across the
entire opening.
3 Check all cable connectors for any sign of unseating.
4 Verify that one or both AC cords are firmly seated at both ends. Make sure that the spring bail
power cord retainers on the rear of the frame are in place.
Intake Filter Screen Cleaning
The intake filter is located on the front door assembly of the frame. To access the filter, simply open
the door by releasing the two thumbscrew locks. Slide the filter up and to the right to remove it.
This process might be easier if you remove the entire door. To remove it, simply open the door and
lift it straight up. The system can be operated safely with the door removed for short periods of
time.
S
NOTE: Be sure to replace the door when done. This ensures that air entering the frame is prop-
erly filtered.
If the filter is only lightly contaminated with debris, clean it with a vacuum cleaner or dry com-
pressed air. Remove loose debris and dirt with a vacuum cleaner or by blowing air from the clean
side to the dirty side. For filters that are badly clogged, a rinse with cold water may prove effective.
You can also wash the filter with warm water and mild detergent. In any case, make sure the filter is
completely dry before reinstalling it.
Battery Replacement
A CR2330 lithium coin cell is located on the front edge of a router control module and at the front
edge of an MCPM-SD or -HD. These batteries provides power to maintain the RAM contents when
power is lost.
S
Some MCPMs have a battery and some do not. MCPMs do not need a battery. There is no need
to replace a battery in the MCPM.
Under continual power, the battery should last several years or more. If the module is frequently
powered down, you should replace the battery every 6 months. A red LED, located directly above
the battery holder in the control card illuminates if the battery is low. The MCPM-SD and -HD have
no obvious battery LED.
