8.2.5 APPLYING POWER
After all equipment has been installed and wired, apply power to each shelf by re-installing the power
supply modules.
1. Re-insert the main and (if provided) redundant power supply modules into the Main Shelf.
2. If the multiplexer is equipped with a Repeater Shelf using separate Repeater Shelf power
supplies, re-insert the main and (if provided) redundant power supply modules into the
Repeater Shelf.
3. If a local alarm comes on, activate the IMUX 2000 alarm cut-off by turning on the ACO switch
located on the power supply module.
If the shelf is equipped with redundant power supplies, turn on both ACO
switches.
4. Check the indicators on each power supply.
On each power supply, the POWER indicator should be lit, and the POWER FAIL
indicator should not be lit.
If no indicators are illuminated on any power supply, then both power modules
have failed, both fuses have blown, or (most likely) power has not been wired to
the shelf. If the POWER indicators turn on, but the POWER FAIL indicator on
one power supply is also on, then that power module is not functioning or has a
blown fuse.
5. Verify that the mode of each CM4 module is displayed for several seconds after power is first
applied.
Do not be concerned at this point if the mode setup(s) are not correct.
