Reinstalling Components in the Chassis

After the services gateway chassis is installed in the rack, you reinstall the removed components before booting and configuring it. The following procedures describe how to reinstall components in the chassis, first in the rear and then in the front:

Reinstalling the Power Supplies

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

  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. For more information about ESD, see Preventing Electrostatic Discharge Damage.
  2. For an AC-powered services gateway, switch the AC switch on the power supply slot to the off position (O). For a DC-powered services gateway, switch the circuit breaker on the power supply to the OFF position.

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

  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 faceplate (see Figure 82).
  4. Tighten the captive screws.

Reinstalling the Fan Tray

To reinstall the fan tray, use the following procedure:

  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. For more information about ESD, see Preventing Electrostatic Discharge Damage.
  2. 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.
  3. Tighten the captive screws on each side of the fan tray faceplate to secure it in the chassis.

Reinstalling SCBs

To reinstall an SCB, follow this procedure for each SCB (see Figure 84):

Caution: Before removing or replacing an SCB, ensure that the ejector handles are stored vertically and pressed toward the center of the SCB.

  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. For more information about ESD, see Preventing Electrostatic Discharge Damage.
  2. Carefully align the sides of the SCB with the guides inside the chassis.
  3. Slide the SCB into the chassis, carefully ensuring that it is correctly aligned.
  4. Grasp both ejector handles and rotate them simultaneously clockwise until the SCB is fully seated.
  5. Place the ejector handles in their proper position, horizontally and toward the center of the board.

Reinstalling IOCs and SPCs

To reinstall the IOCs and SPCs, follow this procedure for each card (see Figure 85):

  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. For more information about ESD, see Preventing Electrostatic Discharge Damage.
  2. Place the card on an antistatic mat or remove it from its electrostatic bag.
  3. Identify the slot on the services gateway where it will be installed.
  4. Verify that each fiber-optic has a rubber safety cap covering the transceiver. If it does not, cover the transceiver with a safety cap.
  5. Orient the card so that the faceplate faces you.
  6. Lift the card into place and carefully align the sides 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. Grasp both ejector handles and rotate them clockwise simultaneously until the card is fully seated.
