fiberĆoptic link with the transceiver hub. 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 signal integrity.
WARNING
TURN OFF AND LOCKOUT OR TAG POWER TO BOTH THE MASTER OR SLAVE
DROP AND THE CORRESPONDING RACKĆMOUNTED OR STANDĆALONE
TRANSCEIVER 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 TO ANSI PUBLICATION Z136.1Ć1981. FAILURE TO
OBSERVE THIS PRECAUTION COULD RESULT IN BODILY INJURY.
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.
The opposite end of the transceiver contains a sixĆscrew terminal
block for operating power and signal connections. See section K2.2
for the terminal block designations. The 24VDC required for
transceiver operation must be provided externally. Note that terminal
6 (-24V) is internally connected to the transceiver enclosure.
A jumper between terminals 3 and 4 is used to connect a builtĆin 120
ohm terminating load between terminals 1 and 2. This jumper must
be used on all StandĆAlone Transceivers.

K1.2.4 FiberĆOptic Rack with Power Supply
The FiberĆOptic Rack and Power Supply (M/N 57C368) provide the
mechanical means of mounting and providing power for up to 10
fiberĆoptic transceivers (M/N 57C367). Technical specifications are
listed in Appendix A.
