RackĆ
Mounted
Transceiver
The RackĆMounted Transceiver (M/N 57C367) is simply the
StandĆAlone Transceiver (M/N 57C365) attached to an adapter
plate, which allows it to be mounted in the Transceiver Rack
(M/N 57C368).
The adapter faceplate contains one green LED which, when lit,
indicates the transceiver is receiving power. Two captive
screws on the faceplate secure the transceiver to the rack.
A fourĆscrew terminal block is provided on the back of the
adapter for transceiverĆtoĆtransceiver data transmission via
twistedĆpair wire. A 2Ćpin plug on the back of the adapter
provides connection to the rack backplane for input power.
The RackĆMounted Transceiver is shipped with the connections
made between the fourĆscrew terminal block and plug on the
back of the adapter and the sixĆscrew terminal block on the
transceiver. A jumper between terminals 3 and 4 on the
sixĆscrew terminal block is used to connect a builtĆin 120Ćohm
terminating load between terminals 1 and 2. This jumper must
be connected on transceivers at the extreme ends of the rack.
Receive and transmit ports labeled R" and T", respectively,
are provided on the back of the transceiver for connection to
the fiberĆoptic link with the StandĆAlone Transceiver. The
transceiver is shipped with dust caps covering the fiberĆoptic
ports. The dust caps should not be removed until the
fiberĆoptic cables are installed and should be replaced if the
cables are disconnected, to prevent dust accumulation and the
resulting loss of the signal integrity. The green LEDs on either
side of each connector indicate the status of the receiver and
transmitter and will flicker as data is received and transmitted
by the transceiver.
WARNING
TURN OFF AND LOCKOUT OR TAG POWER TO BOTH THE
RACK CONTAINING THE NETWORK COMMUNICATIONS
MODULE AND THE TRANSCEIVER (RACKĆMOUNTED OR
STANDĆALONE) BEFORE VIEWING THE FIBERĆOPTIC
CABLE OR TRANSMITTER UNDER MAGNIFICATION.
VIEWING A POWERED FIBERĆOPTIC TRANSMITTER OR
CONNECTED CABLE UNDER MAGNIFICATION MAY
RESULT IN DAMAGE TO THE EYE. FOR ADDITIONAL
INFORMATION,
REFER
