SHELF/RACK ALARM CONNECTION

A.2.3
Each MDR-8000 rack equipped with the Power Distribution Unit (PDU) 695-6200-001/002 has
a visual rack alarm indicator to report a shelf failure. In order to activate a rack alarm visual
indicator on the PDU, the shelf alarm output from each MDR-8000 shelf must be hardwired to
connector J1 on the PDU. The shelf alarm is provided on alarm connector J305 pin 24 (major/
visual alarm). A wire-wrap adapter (PN 695-4171-002) for connector J305 is available. Insu-
lated 22-gauge solid copper wire is recommended for connecting to the wire-wrap adapter. To
attach to J1 (2-pin connector) on the PDU, use 2-position socket housing PN 372-0114-140 and
socket contact PN 372-0114-390. See Figure A-6 for shelf-to-rack alarm wiring.
Each MDR-8000 rack equipped with PDU 3EM13317AA has a blown fuse alarm visual
indicator and a Form C relay alarm output (J4, J5, and J6) for connection to customer
alarm equipment.
An optional Fuse and Shelf alarm plug-in assembly is available to provide shelf alarm con-
nections requiring Form C relays. The alarm inputs (major and minor) must be hard wired
to J3 on the PDU. The alarms are provided on alarm connector J305 pin 24 (major/visual
alarm) and pin 50 (minor/audible alarm) of each shelf. A wire-wrap adapter (PN 695-4171-
002) for connector J305 is available. Insulated 22-gauge solid copper wire is recommended
for connecting to the wire-adapter and also to J3 on the PDU. Alarm outputs are transmit-
ted to customer equipment via Form C relay outputs (J4, J5, J6, relays 1 through 8). This
option also includes the blown fuse alarm indicator and Form C relay alarm output (J4, J5,
and J6 – relay 9). See Figure A-6 for typical shelf to PDU alarm wiring.
