Connecting a Fiber-Optic Cable to the BEB
4. Insert the connector into the BEB enclosure receptacle until both cantilever arms of
the connector click into the transceiver device mounted on the BEB enclosure.
5. Route the fiber-optic cable into the upper and lower cable clamps on the module
side wall, and fasten the clamps. Route the cable into the extrusion channel at the
point where the cutout in the rear bezel door allows the cable to pass into the
channel when the door is closed. This cutout prevents the cable from being
pinched when the door is closed. Route the cable downward into the channel until
you reach the channel bottom (see Figure 3-16).
6. Repeat Steps 1 through 5 for the second tape drive in the module and for any other
modules in the modular tape subsystem.
7. After fiber-optic cables have been installed into all the tape drive CRUs in all the
modules, install the extrusion guides in the channels. The extrusion guides
prevent the cables from coming out of the channel. The extrusion guides are
flexible and slide onto the ridges of the channel (see Figure 3-16).
8. Bring each module online. See Bringing the Tape Drives Online After Installation
on page 3-39.
9. Reinstall the rear bezel door for each module, making sure that any AC power
cords or cables are routed properly through the door cutouts and into the extrusion
channels on the sides of the module.
Caution. Make sure that none of the fiber-optic cables becomes pinched during installation.
Do not “loop” the cable within the channel guides. Fiber-optic cable should not be bent more
than the maximum bend radius of 10 centimeters (4 inches).
Caution. Installing the extrusion guides and routing fiber-optic cable behind them prevents the
cable from becoming pinched or severed by the rear bezel door when the door is closed.
