Juniper SRX4600

Maintaining SRX4600 Services Gateway Network Cables
Purpose
For optimum services gateway performance, verify the condition of the network cables.
Action
On a regular basis:
•
Secure excess cable in tidy loops that do not obstruct access to the services gateway. Do not allow
fastened loops of cable to dangle from the connector, because this stresses the cable at the fastening
point. Putting fasteners on the loops helps maintain their shape.
•
Keep the cable connections clean and free of dust and other particles, which can cause drops in the
received power level. Always inspect cables and clean them if necessary before connecting an interface.
•
Label both ends of the cables to identify them.

Maintaining Fiber-Optic Cables
Fiber-optic cables connect to optical transceivers that are installed in Juniper Networks devices.
To maintain fiber-optic cables:
•
When you unplug a fiber-optic cable from a transceiver, place rubber safety caps over the transceiver
and on the end of the cable.
•
Anchor fiber-optic cables to prevent stress on the connectors. When attaching a fiber-optic cable to a
transceiver, be sure to secure the fiber-optic cable so that it does not support its own weight as it hangs
to the floor. Never let a fiber-optic cable hang free from the connector.
•
Avoid bending fiber-optic cables beyond their minimum bend radius. Bending fiber-optic cables into
arcs smaller than a few inches in diameter can damage the cables and cause problems that are difficult
to diagnose.
•
Frequent plugging and unplugging of fiber-optic cables in and out of optical instruments can damage
the instruments, which are expensive to repair. Attach a short fiber extension to the optical equipment.
