3. Unplug the cable from the cable connector port. If the PIC uses fiber-optic cable,
immediately cover each transceiver and the end of each cable with a rubber safety cap.
Do not look directly into the ends of fiber-optic cables or into the
transceivers on the interface faceplate. Single-mode fiber-optic cable
and the interfaces that use it (such as ATM and SONET/SDH interfaces)
emit laser light that can damage your eyes.
Do not leave a fiber-optic transceiver uncovered except when inserting
or removing cable. The safety cap keeps the port clean and prevents
accidental exposure to laser light.
4. Remove the cable from the cable management system and detach it from the
destination port.
Install a PIC Cable
To install a PIC cable, follow this procedure (see Figure 32):
1. Have ready a length of the type of cable used by the PIC. For cable specifications, see
the M5 and M10 Internet Routers PIC Guide.
2. If the PIC cable connector port is covered by a rubber safety plug, remove the plug.
Do not look directly into the ends of fiber-optic cables or into the
transceivers on the interface faceplate. Single-mode fiber-optic cable
and the interfaces that use it (such as ATM and SONET/SDH interfaces)
emit laser light that can damage your eyes.
Do not leave a fiber-optic transceiver uncovered except when inserting
or removing cable. The safety cap keeps the port clean and prevents
accidental exposure to laser light.
