Removing Cards Before Installing an SRX5400 Firewall Without a Lift

The firewall holds up to four cards (MPCs, SCB, and SPCs), which are installed horizontally in the front of
the device. Each card weighs up to 18.3 lb (8.3 kg), be prepared to accept its full weight.
To remove a card (see Figure
1. 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.
2. Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD
grounding point.
3. Label the cables connected to each port on the card so that you can later reconnect the cables to the
correct ports.
4. 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.
LASER 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.
