After the mounting hardware is installed, proceed to Installing the SRX5800 Services Gateway Chassis in the Rack.

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 3):

  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 4):

  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.
Figure 4: Removing the Cable ManagerRemoving the Cable Manager

Removing Fan Trays Before Installing the SRX5800 Services Gateway Chassis

To remove the upper or bottom fan tray (see Figure 5 and Figure 6, which illustrate the upper and bottom 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.
Figure 5: Removing an Upper Fan TrayRemoving an Upper Fan Tray
Figure 6: Removing the Bottom Fan TrayRemoving the Bottom Fan Tray

Removing Cards Before Installing the SRX5800 Services Gateway Chassis

The services gateway holds up to twelve cards (IOCs, Flex IOCs, MPCs, SCBs, 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 7):

  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.
    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.

    CAUTION:

    Do not leave a fiber-optic transceiver uncovered except when you are inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

    CAUTION:

    Avoid bending a 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. For SCBs, observe these points regarding the ejector handles:
    • When removing or inserting an SCB, ensure that the SCBs or blank panels in adjacent slots are fully inserted to avoid hitting them with the ejector handles. The ejector handles require that all adjacent components be completely inserted so the ejector handles do not hit them, which could result in damage.

    • The ejector handles have a center of rotation and need to be stored toward the center of the board. Ensure the long ends of the ejectors located at both the top and the bottom of the board are vertical and pressed as far as possible toward the center of the board. Once you have installed an SCB, 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.

    • To insert or remove the SCB card, slide the ejector across the SCB horizontally, rotate it, and slide it again another quarter of a turn. Turn the ejector again and repeat as necessary. Use the indexing feature to maximize leverage and to avoid hitting any adjacent components.

  6. Simultaneously turn both the ejector handles counterclockwise to unseat the card.
  7. Grasp the handles and slide the card straight out of the card cage halfway.
  8. 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.

Figure 7: Removing a Card (IOC Shown, Other Card Types Similar)Removing a Card (IOC Shown, Other Card Types Similar)

Installing the SRX5800 Services Gateway Chassis in the Rack

Because of the services gateway’s size and weight—up to 400 lb (182 kg) depending on the configuration—you must install the services gateway using a mechanical lift.

CAUTION:

Before front mounting the services gateway in a rack, have a qualified technician verify that the rack is strong enough to support the services gateway's weight and is adequately supported at the installation site.

To install the services gateway using a lift (see Figure 8):

  1. Ensure the rack is in its permanent location and is secured to the building. Ensure that the installation site allows adequate clearance for both airflow and maintenance.
  2. Load the services gateway onto the lift, making sure it rests securely on the lift platform.
  3. Using the lift, position the services gateway in front of the rack or cabinet, centering it in front of the mounting shelves.
  4. Lift the chassis approximately 0.75 in. above the surface of the mounting shelves and position it as close as possible to the shelves.
  5. Carefully slide the services gateway onto the mounting shelves so that the bottom of the chassis and the mounting shelves overlap by approximately two inches.
  6. Slide the services gateway onto the mounting shelves until the center-mounting brackets or front-mounting flanges contact the rack rails. The shelves ensure that the holes in the center-mounting brackets and the front-mounting flanges of the chassis align with the holes in the rack rails.
  7. Move the lift away from the rack.
  8. To install the services gateway in an open-frame rack, install a mounting screw into each of the open mounting holes aligned with the rack, starting from the bottom.
  9. Visually inspect the alignment of the services gateway. If the services gateway is installed properly in the rack, all the mounting screws on one side of the rack should be aligned with the mounting screws on the opposite side and the services gateway should be level.

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 9, which shows the installation of the DC power supplies):

  1. 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.

  2. Ensure that the release lever below the empty power supply slot is locked in the counterclockwise position (see Figure 9).

    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.

  3. 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.

  4. 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.
  5. Let go of the locking pin in the release lever. Ensure that the pin is seated inside the corresponding hole in the chassis.

Reinstalling Cards After Installing the SRX5800 Services Gateway Chassis

To reinstall cards (IOCs, Flex IOCs, MPCs, SPCs, and SCBs (see Figure 12):

  1. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  2. Take each card to be installed out of its electrostatic bag and identify the slot on the card cage where it will be connected.
  3. 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.
  4. Locate the slot in the card cage in which you plan to install the card.
  5. Ensure the card is right-side up, with the text on the faceplate of the card facing upward.
  6. Lift the card into place and carefully align first the bottom, then the top of the card with the guides inside the card cage.
  7. Slide the card all the way into the card cage until you feel resistance.
  8. For SCBs, observe these points regarding the ejector handles:
    • When removing or inserting an SCB, ensure that the SCBs or blank panels in adjacent slots are fully inserted to avoid hitting them with the ejector handles. The ejector handles require that all adjacent components be completely inserted so the ejector handles do not hit them, which could result in damage.

    • The ejector handles have a center of rotation and need to be stored toward the center of the board. Ensure the long ends of the ejectors located at both the top and the bottom of the board are vertical and pressed as far as possible toward the center of the board. Once you have installed an SCB, 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.

    • To insert or remove the SCB card, slide the ejector across the SCB horizontally, rotate it, and slide it again another quarter of a turn. Turn the ejector again and repeat as necessary. Use the indexing feature to maximize leverage and to avoid hitting any adjacent components.

  9. Grasp both ejector handles and rotate them simultaneously clockwise until the card is fully seated.
  10. 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 cables hang free from the connector. Do not allow the fastened loops of a cable to dangle, which stresses the cable at the fastening point.

    CAUTION:

    Avoid bending a 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.
