To remove an SPC (see Figure 53 on page
Have ready a replacement SPC or blank panel and an antistatic mat for the SPC. Also
1.
have ready rubber safety caps for each SPC you are removing that uses an optical
interface.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
2.
the strap to one of the ESD points on the chassis.
Power off the services gateway.
3.
Label the cables connected to each port on the SPC so that you can later reconnect
4.
the cables to the correct ports.
Disconnect the cables from the SPC. If the SPC uses fiber-optic cable, immediately
5.
cover each transceiver and the end of each cable with a rubber safety cap. Arrange
the disconnected cables in the cable management system to prevent the cables from
developing stress points.
WARNING: Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable
connected to a transceiver emit laser light that can damage your eyes.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when
you are inserting or removing cable. The safety cap keeps the port clean
and prevents accidental exposure to laser light.
CAUTION: Avoid bending fiber-optic cable beyond its minimum bend
radius. An arc smaller than a few inches in diameter can damage the cable
and cause problems that are difficult to diagnose.
CAUTION: Do not let fiber-optic cable hang free from the connector. Do
not allow fastened loops of cable to dangle, which stresses the cable at
the fastening point.
Simultaneously turn both of the ejector handles counterclockwise to unseat the SPC.
6.
Grasp the handles and slide the SPC straight out of the card cage halfway.
7.
Place one hand around the front of the SPC and the other hand under it to support it.
8.
Slide the SPC completely out of the chassis, and place it on the antistatic mat or in
the electrostatic bag.
