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.
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
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
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.
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.
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
The weight of the SPC is concentrated in the back
end. Be prepared to accept the full weight—up to 13.1 lb (5.9 kg)—as
you slide the SPC out of the chassis.
When the SPC is out of the chassis, do not hold it
by the ejector handles, bus bars, or edge connectors. They cannot
support its weight.
Do not stack SPCs on top of one another after removal.
Place each one individually in an electrostatic bag or on its own
antistatic mat on a flat, stable surface.
If you are not reinstalling an SPC into the
emptied slot within a short time, install a blank panel over the slot
to maintain proper airflow in the card cage.
