Power Failure
The Access System 2000 shelf unit typically has two power
supplies for redundant operation. This arrangement maintains T1
network transmission service if one of the power supplies fails.
Each Dual-line Shelf can use two redundant 115 Vac or 48 Vdc
power supplies. If HDM 2180 or HDM 2182 modules are used in a
Dual-line shelf, use of two power supplies is suggested.
If a Multi-line Shelf loses power, the front panel power LED of the
associated power supplies will go out, and all LEDs on the other
modules go out. If this condition exists, check the power source.
DC Power If one power supply fails in a Multi-line Shelf powered by -48 Vdc,
check for a blown fuse in the fuse panel. Check for -48 Vdc at the
backplane for that power supply. The -48V and battery return
connections are made at terminal strip TB1 in back of the shelf.
