Removing an SPC
An SPC weighs up to 13.1 lb (5.9 kg). Be prepared to accept its full weight.
To remove an SPC (see Figure 61 on page 129):

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 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.

Replacing SPCs
Have ready a replacement SPC or blank panel and an antistatic mat for the SPC.
Also 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 the strap to one of the ESD points on the chassis. For more information
about ESD, see "Preventing Electrostatic Discharge Damage" on page 152.
Power off the device as described in "Powering Off the Services Gateway" on
page 70.
Label the cables connected to each port on the SPC so that you can later reconnect
the cables to the correct ports.
Disconnect the cables from the SPC. If the SPC uses fiber-optic cable, immediately
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.
Simultaneously turn both of the ejector handles counterclockwise to unseat the
SPC.
Grasp the handles and slide the SPC straight out of the card cage halfway.
Place one hand around the front of the SPC and the other hand under it to support
it. Slide the SPC completely out of the chassis, and place it on the antistatic mat
or in the electrostatic bag.
