Reinstalling Components in the SRX5800 Services Gateway Chassis After Installing It in the Rack
After the services gateway is installed in the rack, reinstall the removed components before booting and configuring the services gateway. You reinstall components first in the rear of the chassis, and then in the front:

Reinstalling Power Supplies After Installing the SRX5800 Services Gateway Chassis
Reinstall the rightmost power supply first and then work your way to the left. To reinstall the AC or DC power supplies, follow this procedure for each power supply (see Figure 1, which shows the installation of the DC power supplies):
- Attach an ESD grounding strap to your bare wrist,
and connect the strap to one of the ESD points on the chassis.
Verify that the power supplies are switched off:
- For an AC-powered services gateway, verify that the AC input switch on the chassis above each AC power supply is in the off (O) position. If the services gateway is equipped with high-capacity AC power supplies, also verify that the AC input switch on each power supply is in the off (O) position.
- For DC-powered services gateway, verify that the DC circuit breaker on each power supply faceplate is in the off (O) position.
We recommend verifying that the power supplies are switched off even though they are not connected to power sources.
- Ensure that the release lever below the empty power
supply slot is locked in the counterclockwise position (see Figure 1).
If necessary, pull the spring-loaded locking pin in the release lever away from the chassis and turn the release lever counterclockwise until it stops. Let go of the locking pin in the release lever. Ensure that the pin is seated inside the corresponding hole in the chassis.
- Using both hands, slide the power supply straight
into the chassis until the power supply is fully seated in the chassis
slot. The power supply faceplate should be flush with any adjacent
power supply faceplates.
The small tab on the metal housing that is controlled by the release lever must be inside of the corresponding slot at the bottom of the power supply. This tab is used to pull the power supply down in the chassis slot, prior to removing the power supply.
- While firmly pushing the handle on the power supply faceplate with one hand, use your other hand to pull the spring-loaded locking pin in the release lever away from the chassis and turn the release lever clockwise until it stops.
- Let go of the locking pin in the release lever. Ensure that the pin is seated inside the corresponding hole in the chassis.

Reinstalling Fan Trays After Installing the SRX5800 Services Gateway Chassis
To reinstall the fan trays (see Figure 2 and Figure 3):
- Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Grasp the fan tray on each side and insert it straight into the chassis. Note the correct orientation by the "this side up" label on the top surface of the fan tray.
- Tighten the captive screws on each side of the fan tray faceplate to secure it in the chassis.
- Lower the standard cable manager back into position, if necessary.

Reinstalling SCBs After Installing the SRX5800 Services Gateway Chassis
To reinstall an SCB (see Figure 4):
 | Caution: Before removing or replacing an SCB, ensure that the ejector handles are stored vertically and pressed toward the center of the SCB. |
- Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Carefully align the sides of the SCB with the guides inside the chassis.
- Slide the SCB into the chassis until you feel resistance, carefully ensuring that it is correctly aligned.
- Grasp both ejector handles and rotate them simultaneously clockwise until the SCB is fully seated.
- Place the ejector handles in their proper position, vertically and toward the center of the board. To avoid blocking the visibility of the LEDs position the ejectors over the PARK icon.

Reinstalling IOCs, Flex IOCs, and SPCs After Installing the SRX5800 Services Gateway Chassis
To reinstall IOCs, Flex IOCs, and SPCs (see Figure 5):
- Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Take each card to be installed out of its electrostatic bag and identify the slot on the card cage where it will be connected.
- Verify that each fiber-optic port has a rubber safety cap covering the transceiver. If it does not, cover the transceiver with a safety cap.
- Locate the slot in the card cage in which you plan to install the card.
- Ensure the card is right-side up, with the text on the faceplate of the card facing upward.
- Lift the card into place and carefully align first the bottom, then the top of the card with the guides inside the card cage.
- Slide the card all the way into the card cage until you feel resistance.
- Grasp both ejector handles and rotate them simultaneously clockwise until the card is fully seated.
- Insert the appropriate cable into the cable connector
ports on each card. Secure each cable so that it is not supporting
its 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.

Reinstalling the Cable Manager After Installing the SRX5800 Services Gateway Chassis
To reinstall the cable manager (see Figure 6):
- Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Position the cable manager on the studs on the lower front of the chassis.
- Insert the nuts on the corners in the cable manager onto the studs on the chassis.
- Using a 7/16-in. nut driver, tighten the nuts securely.
