Installing the T320 Chassis in the Rack Manually

Caution: If you are installing two routers in one rack, install the lower one first. Installing a router in the upper position in a rack or cabinet requires a 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.

Caution: Lifting the chassis and mounting it in a rack requires four people. The empty chassis weighs approximately 131.4 lb (59.6 kg).

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. 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 1). Tighten the screws, using a Phillips (+) screwdriver, number 2.

3. Position the router in front of the rack or cabinet, centering it in front of the mounting shelves. Use a pallet jack if one is available.

   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.

4. With two people in the front and two people in the back, hold onto the bottom of the chassis and carefully lift it onto the mounting shelves.

   Warning: To prevent injury, keep your back straight and lift with your legs, not your back. Avoid twisting your body as you lift. Balance the load evenly and be sure that your footing is solid.

5. 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.
6. Install the mounting screws:
   • Four-post rack or cabinet—Install a mounting screw through 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.
7. Loosen the captive screws on the installation handle completely, and remove the handle from the chassis.
8. 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.
