2.6.2 Connect Fiberoptic Cables
Before turning on the AC (or DC) power to the chassis, connect the fiberoptic cables at the rear panel.
During installation of the fiberoptic cables, each fiber should have been labelled as to which Remote
Transceiver it is to be connected to and whether it is for transmit or receive. The transmit or downlink
fibers are connected to the optical outputs on the rear panel. These are the red connectors with the laser
light warning labels. Make sure that the connectors used are associated with an active plug-in installed in
the chassis.
First, clean the tip of the connector on the cable according to the procedures in 2.2.2 above. Lift the spring
loaded cover on the Hub Shelf rear panel connector and, after orienting the connector so that the “key” on
the connector aligns with the slot in the mating adapter on the Hub rear panel, push in the SC/UPC cable
connector until firmly seated (the connector may or may not “click” into place; do not push too hard!!).

2.6.3 Indentifying Remote Locations
The front panel of each Plug-In has two 1.75” x 0.5” (4.4 cm x 1.3 cm) outlines labelled A and B which
can be used to affix standard “address” size labels (Avery 5167) to designate which Remote Transceiver is
connected to that path. These labels should correspond to the electronic names assigned to each path
through the front panel Craft serial port.

2.6.4 Serial Bus, Telephone and Local Alarm Connections
If more than one Hub Shelf is being used, connect the SERIAL DATA ports together using CAT-5
jumpers with RJ-45 connectors. The two SERIAL DATA ports on the rear panel are connected together;
two are provided to permit the use of simple jumpers when daisy-chaining several units.
Connect the LINE port to a POTS telephone jack for the dial-up modem connection.
If it is being used, connect the chassis to the local OA&M interface by way of the 37 pin D-Sub connector
on the rear panel of the Hub Shelf (see section 2.3: System Alarms).

2.6.5 Mains Power and Fuses
Turn on the chassis power. The AC powered version of the Hub Shelf operates on 100 to 240VAC. The
rear panel IEC receptacle is dual fused. The fuses used are FUSE, TIME LAG, 2 AMP, SLO-BLO

CAUTION: DOUBLE POLE/NEUTRAL FUSING
Certified power cords and ac plugs, appropriate for the country where equipment is installed,
shall be used for continued safety compliance.
Powering up the chassis will “light up” the fiber allowing those installing the Remote
Transceivers to identify the transmit and receive cables using an IR sensitive card (see Recommended
Tools) to see which fiber is emitting light. The fiber emitting light at the Remote Transceiver end is the
transmit path and is connected to the OPTICAL IN connector on the Remote Transceiver (after proper
cleaning; see section 2.2.2).
