Removing an SRX5600 Services Gateway SPC
An SPC weighs up to 18.3 lb (8.3 kg). Be prepared to accept its full weight.
To remove an SPC (see Figure 132 on page 320 ):
1. 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.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis.
3. 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.
4. Physically turn off the power and remove the power cables from the chassis.
5. Label the cables connected to each port on the SPC so that you can later reconnect the cables to the
correct ports.
6. 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.
