Replacing SRX5600 Services Gateway SPCs
To replace an SPC, perform
the following procedures:
- Removing an SRX5600 Services Gateway SPC
- Installing an SRX5600 Services Gateway SPC
Removing an SRX5600 Services Gateway SPC
An SPC weighs up to 13.1 lb (5.9 kg). Be prepared
to accept its full weight.
To remove an SPC (see Figure 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.
- Attach an electrostatic discharge (ESD) grounding
strap to your bare wrist, and connect the strap to one of the ESD
points on the chassis.
- Power-off the services gateway.
- 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
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 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. |
 | Caution:
Do not let fiber-optic cable hang free from the connector.
Do not allow fastened loops of cable to dangle, which stresses the
cable at the fastening point. |
- 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
bag.
 | Caution:
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 empty slot
within a short time, install a blank panel over the slot to maintain
proper airflow in the card cage.

Installing an SRX5600 Services Gateway SPC
To install an SPC (see Figure 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.
- If you have not already done so, power off the device.
- Place the SPC on an antistatic mat or remove it
from its electrostatic bag.
- Identify the slot on the services gateway where
it will be installed.
- Verify that each fiber-optic transceiver is covered
with a rubber safety cap. If it does not, cover the transceiver with
a safety cap.
- Orient the SPC so that the faceplate faces you, the text
on the card is right-side up, and the EMI strip is on the right-hand
side.
- Lift the SPC into place and carefully align the
right and left edges of the card with the guides inside the card cage.
- Slide the SPC all the way into the card cage until
you feel resistance.
- Grasp both ejector handles and rotate them clockwise
simultaneously until the SPC is fully seated.
- If the SPC uses fiber-optic cable, remove the rubber
safety cap from each transceiver and cable.
 | 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. |
- Insert the appropriate cables into the cable connector
ports on each SPC (see Figure 3). Secure the cables so that they are not supporting their
own weight. Place excess cable out of the way in a neatly coiled loop,
using the cable management system. Placing fasteners on a loop helps
to maintain its shape.
 | Caution:
Do not let fiber-optic cable hang free from the connector.
Do not allow fastened loops of cable to dangle, which stresses the
cable at the fastening point. |
 | 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. |
- Power-on the services gateway. The OK LED
on the power supply faceplate should blink, then light steadily.
- Verify that the SPC is functioning correctly by
issuing the show chassis fpc and show chassis fpc
pic-status commands.
