Removing Components from the SRX5800 Chassis Before Installing It in the Rack

Before installing the services gateway in the rack, you must first remove components from the chassis to make it light enough to safely maneuver into the rack. With components removed, the chassis weighs approximately 150 lb (68 kg). You reinstall the components into the chassis after it is installed in the rack.

Removing the Power Supplies Before Installing the SRX5800 Services Gateway Chassis

Remove the leftmost power supply first and then work your way to the right. To remove each AC or DC power supply (see Figure 1):

1. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.

2. Switch off the services gateway power supplies:

   • For an AC-powered services gateway, move the AC input switch on the chassis above each AC power supply to the off  (O) position. If the services gateway is equipped with high-capacity AC power supplies, you must also move the AC input switch on each power supply to the off  (O) position.
   • For DC-powered services gateway, move the DC circuit breaker on each power supply faceplate to the off (O) position.
   We recommend switching off the power supplies even though they are not connected to power sources.
3. While grasping 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 counterclockwise until it stops.
4. Let go of the locking pin in the release lever. Ensure that the pin is seated inside the corresponding hole in the chassis.
5. Pull the power supply straight out of the chassis.

   Warning: Do not touch the power connector on the top of the power supply. It can contain dangerous voltages.

Removing the Cable Manager Before Installing the SRX5800 Services Gateway Chassis

To remove the cable manager (see Figure 2):

1. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
2. Using a 7/16-in. nut driver, unscrew the nuts on the corners of the cable manager.
3. Grasp the bottom of the cable manager and pull it straight out from the studs on the front of the chassis.

Removing Fan Trays Before Installing the SRX5800 Services Gateway Chassis

To remove the upper or lower fan tray (see Figure 3 and Figure 4, which illustrate the upper and lower fan trays):

1. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
2. Loosen the captive screw on each side of the fan tray faceplate.
3. Grasp both sides of the fan tray and pull it out approximately 1 to 3 inches.
4. Press on the two latches located on the inside of the fan tray to release the fan tray from the chassis.
5. Place one hand under the fan tray to support it and pull the fan tray completely out of the chassis.

Removing SCBs Before Installing the SRX5800 Services Gateway Chassis

To remove the SCBs (see Figure 5):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
3. Rotate the ejector handles simultaneously counterclockwise to unseat the SCB.
4. Grasp the ejector handles and slide the SCB about halfway out of the chassis.
5. Place one hand underneath the SCB to support it and slide it completely out of the chassis. Place it on the antistatic mat.

   Caution: Do not stack hardware components on one another after you remove them. Place each component on an antistatic mat resting on a stable, flat surface.

6. Repeat the procedure for each SCB.

Removing IOCs, Flex IOCs, and SPCs Before Installing the SRX5800 Services Gateway Chassis

The services gateway holds up to twelve IOCs, Flex IOCs, and SPCs, which are installed horizontally in the front of the device. Each card weighs up to 13.1 lb (5.9 kg), be prepared to accept its full weight.

To remove an IOC, a Flex IOC, or an SPC (see Figure 6):

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 strap to one of the ESD points on the chassis.
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.

   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.

5. Simultaneously turn both the ejector handles counterclockwise to unseat the IOC.
6. Grasp the handles and slide the card straight out of the card cage halfway.
7. 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.

   Caution: The weight of the card 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 card out of the chassis. When the card 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 cards 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.
