Installing the T320 Router Using a Mechanical Lift

 

Removing the T320 Power Supplies

To remove the power supplies:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site.
  2. Switch the circuit breaker on the power supply faceplate to the off position (O). We recommend this even though the power supplies are not connected to power sources.
  3. Loosen the captive screws on the lower corners of the power supply faceplate completely. Twist the ejector handles on the upper corners of the faceplate counterclockwise to unseat the power supply.
  4. Twist the ejector handles on the upper corners of the faceplate counterclockwise to unseat the power supply.
  5. Grasp the handle on the power supply faceplate and pull firmly to start removing the power supply. Slide it halfway out of the chassis (see Figure 1).
  6. Place one hand underneath the power supply to support it and slide it completely out of the chassis.Caution

    Each power supply weighs approximately 12 lb (5.4 kg). Be prepared to support the full weight of the power supply as you remove it from the router.

  7. Repeat the procedure for the other power supply.

Attaching the T320 Router Installation Handle

To assist you with the installation of the T320 router, attach the installation handle over the power supply slots of the chassis. To attach the handle:

  1. Attach the installation handle by tightening the captive screws of the handle into the holes previously occupied by the captive screws of the power supplies (see Figure 2).

Installing the T320 Router Using a Mechanical Lift

Caution

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

To install the router using a lift (see Figure 3):

  1. Ensure that 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. For details, see T320 Site Preparation Checklist Requirements.
  2. Load the router onto the lift, making sure it rests securely on the lift platform.Caution

    Do not lift the router using the craft interface, installation handle, or the handles on the sides of the chassis. Use these handles only to help position the router.

  3. Using the lift, position the router 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 router onto the mounting shelves so that the bottom of the chassis and the mounting shelves overlap by approximately two inches.
  6. With one person pulling on the installation handle from the rear of the rack or cabinet while two people push on the front-mounting flanges, slide the router onto the mounting shelves until the center-mounting brackets or front-mounting flanges contact the rack rails or spacer bars (depending on your type of installation). The shelves ensure that the holes in the 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. Install the mounting screws:
    • Four-post rack or cabinet—Install a mounting screw into each of the holes in the spacer bars.

    • 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 router. If the router 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 router should be level.

Removing the T320 Router Installation Handle and Reinstalling the Power Supplies

After you have installed the T320 router, remove the installation handle and reinstall the two power supplies in the chassis by following this procedure, starting with the lower power supply (see Figure 4):

  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 to a T320 Router.
  2. Loosen the captive screws on the installation handle completely, and remove the handle from the chassis.
  3. Make sure that the circuit breaker on the power supply faceplate is in the off position (O).
  4. Using both hands, slide the power supply into the chassis until you feel resistance.
  5. Twist the ejector handles at the upper corners of the power supply faceplate clockwise until they stop.
  6. Tighten the captive screws at the lower corners of the power supply faceplate to secure the power supply in the chassis.
  7. Repeat the procedure for the upper power supply.
