Removing Components from the SRX5600 Chassis Before Installing It Without a Lift

If you cannot use a mechanical lift to install the services gateway (the preferred method), you can install it manually. Before installing the services gateway manually, you must first remove components from the chassis, and reinstall the components the chassis is installed in the rack. With components removed, the chassis weighs approximately 65 lb (29 kg).

Removing the Power Supplies Before Installing the SRX5600 Services Gateway Without a Lift

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

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
2. On an AC-powered services gateway, switch the AC input switch on each power supply to the off  (O) position. On a DC-powered services gateway, Move the DC circuit breaker on each DC power supply to the off (O) position.

   We recommend this even though the power supplies are not connected to power sources.

3. Loosen the captive screws on the bottom edge of the power supply faceplate.
4. Pull the power supply straight out of the chassis.

Removing the Fan Tray Before Installing an SRX5600 Services Gateway Without a Lift

To remove the fan tray (see Figure 2 ):

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
2. Loosen the captive screws on the fan tray faceplate.
3. Grasp the fan tray handle and pull it out approximately 1 to 3 inches.
4. Press the latch located on the inside of the fan tray to release it 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 an SRX5600 Services Gateway Without a Lift

To remove the SCBs (see Figure 3):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
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.
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 an SRX5600 Services Gateway Without a Lift

The services gateway holds up to six IOCs, Flex 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, a Flex IOC, or an SPC (see Figure 4):

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 electrostatic discharge (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 IOC 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.
