Fiber Transceiver Installation
The following instructions apply to installations using the ClearCube Fiber Optic
Extension System and are intended for technicians familiar with fiber optic cabling.
Installing the Fiber Transceiver
Install the Fiber Transceiver in the rack using the included mounting kit and hardware.
It should be mounted so that the front of the Fiber Transceiver is flush with the front of
the Cages immediately above and below the unit. The Fiber Transceiver was
engineered to be placed between two Cages to allow for easy cable routing.
Fiber Transceiver Power Requirements
The Fiber Transceiver has two separate power cords – one for each of the two
internal power supplies. This allows you to achieve maximum redundancy when you
provide two independent power sources for each Transceiver.
NOTE: If only one power cord is connected, the Transceiver is powered only by a
single power supply. Both power inputs must be connected to a power source
in order to have dual redundant supplies. Ideally, each power input is
connected to a power source on a different branch circuit to provide the
greatest reliability.
The maximum steady-state current draw of a single Fiber Transceiver ranges
between 0.5 to 0.7 A at 120 VAC based on the level of user activity. If you are placing
multiple Cages and Transceivers on a single power circuit, make sure that the circuit
can safely handle the combined currents of all the equipment. Therefore, if you place
two Cages (BackPacks) and one Transceiver on a single branch circuit, it must be
able to support a peak current of 25 amps.
Cable Requirements
Each fully loaded Transceiver requires 16 C/Port patch cables with RJ-45 connectors
for connections to the BackPack, and 16 62.5 micron, multi-mode, straight-through
connection fiber optic cables with MT-RJ connectors for connection to the Fiber
CAUTION: The Fiber Transceiver and Fiber C/Port are Laser Class 1
Products. Please refer to Safety Guidelines on page 7 for additional
information.
CAUTION: Make sure your power strips, power grid, and circuit breakers
can safely provide the required current. Ensure that any extension cords
used meet local safety regulations and fire codes. When specifying
uninterruptible power supplies (UPS) be sure to include the Fiber
Transceiver peak current draws in your calculations to ensure the UPS
has adequate capacity.
