Removing the T4000 Power Supplies

To remove the power supplies, start with the upper power supply:

  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. Loosen the captive screws on the lower corners of the power supply faceplate completely.
  3. Twist the ejector handles on the upper corners of the faceplate counterclockwise to unseat the power supply.
  4. 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.Caution

    Be prepared to support the full weight of the power supply as you remove it from the router.

  5. Place one hand underneath the power supply to support it, and slide it completely out of the chassis.
  6. Repeat the procedure for the other power supply.

Attaching the T4000 Installation Handle

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

  1. Place the installation handle over the location of the lower power supply.
  2. Tighten the captive screws of the handle into the holes previously occupied by the captive screws of the power supply (see Figure 2).

Installing the T4000 Chassis in a Rack or Cabinet Using a Mechanical Lift

Because of the router's size and weight—up to 663.6 lb (301.0 kg) depending on configuration—we strongly recommend that you install the router using a lift.

To mount the chassis in the rack or cabinet using a lift (see Figure 3):

  1. If you are installing the router in an open-frame rack, 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 T4000 Clearance Requirements for Airflow and Hardware Maintenance.
  2. Load the router onto the lift, making sure it rests securely on the lift platform.Caution

    Do not lift the router using the 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 chassis 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 chassis onto the mounting shelves so that the bottom of the chassis and the mounting shelves overlap by approximately 2 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 chassis onto the mounting shelves until the 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. If you are installing the router in a four-post rack or cabinet, install a mounting screw and a cage nut into each of the holes aligned with the threaded holes in the spacer bars. If you are installing the router 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 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 T4000 Installation Handle

After you have installed the router, remove the installation handle:

  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. Loosen the captive screws on the installation handle completely.
  3. Remove the handle from the chassis.

Reinstalling the T4000 Power Supplies

After you have removed the installation handle, reinstall the two power supplies in the chassis, starting with the lower power supply (see Figure 5):

  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. Using both hands, slide the power supply into the chassis until you feel resistance.
  3. Twist the ejector handles at the upper corners of the power supply faceplate clockwise until they stop.
  4. Tighten the captive screws at the lower corners of the power supply faceplate to secure the power supply in the chassis.
  5. Repeat the procedure for the upper power supply.
