Ensure you understand how to prevent electrostatic discharge (ESD) damage. See “Prevention of
Electrostatic Discharge Damage” on page 505 .
Ensure that you have the following available:
•
ESD grounding strap
•
Replacement SPC or blank panel
•
Antistatic mat
•
Rubber safety caps for transceivers
To remove an SPC (see Figure 142 on page 363 ):
1. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on
the chassis.
2. Power off the services gateway using the command request system power-off.
user@host#
request system power-off
NOTE: Wait until a message appears on the console confirming that the services stopped.
3. Physically turn off the power and remove the power cables from the chassis.
4. Label the cables connected to each port on the SPC so that you can later reconnect the cables to the
correct ports.
5. 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.
WARNING: Do not look directly into a fiber-optic transceiver or into the ends
of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables 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.
