Removing Iocs And Spcs - Juniper SRX 5600 Hardware Manual

Removing IOCs and SPCs

The services gateway holds up to six IOCs and SPCs, which are installed horizontally
in the front of the device. Each IOCs or SPC weighs up to 13.1 lb (5.9 kg), be prepared
to accept its full weight.
To remove an IOC or SPC (see Figure 80 on page 206):

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.

Appendix F: Installing the Services Gateway Without a Mechanical Lift
Have ready an antistatic mat for the card. Also have ready rubber safety caps
for each port using an optical interface on the card that you are removing.
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.
Label the cables connected to each port on the IOC so that you can later reconnect
the cables to the correct ports.
If a card 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 the ejector handles counterclockwise to unseat the
IOC.
Grasp the handles and slide the card straight out of the card cage halfway.
Place one hand around the front of the card and the other hand under it to
support it. Slide the IOC completely out of the chassis, and place it on the
antistatic mat or in the electrostatic bag.
