Mounting an EX8208 Switch on a Rack or Cabinet Without Using a Mechanical Lift

If you cannot use a mechanical lift to install the switch (the preferred method), you can install it manually.

Caution: The chassis with only the backplane and no other components weighs approximately 89 lb (41 kg). Lifting the chassis and mounting it in a rack or cabinet requires at least three people. The chassis has two handles. Do not lift a fully loaded chassis by the handles; make sure the chassis is empty (contains only the backplane) before you lift it. If two of the people lifting the chassis use the handles to lift it, the third person must lift from the rear of the chassis. The rear of the chassis is heavier than the front of the chassis, so when you lift the chassis by the handles, the chassis tips toward the heavier back end. The person lifting from the back must be aware of this behavior and must be braced to prevent the chassis from tipping over. When lifting the chassis, do not grasp the switch by the blue panel at the top front of the chassis. Doing so can cause the panel to pop off of the switch.

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

Before you install the switch:

1. Prepare the site for installation as described in Site Preparation Checklist for an EX8200 Switch.
2. Ensure the site has adequate clearance for both airflow and hardware maintenance as described in Clearance Requirements for Airflow and Hardware Maintenance for an EX8208 Switch.
3. Unpack the switch as described in Unpacking an EX8200 Switch.
4. Remove all components except the backplane from the chassis. See:

   • Removing an SF Module from an EX8208 Switch
   • Removing a Line Card from an EX8200 Switch
   • Removing a Fan Tray from an EX8208 Switch
   • Removing an AC Power Supply from an EX8200 Switch
5. In a two-post rack, install the power cord tray at the desired position (see Installing the Power Cord Tray in a Rack or Cabinet for an EX8200 Switch). The lip of the power cord tray will support the front of the chassis when you install the switch in the rack.

   In a four-post rack, install the adjustable mounting brackets at the desired position (see Installing Adjustable Mounting Brackets in a Rack or Cabinet for an EX8200 Switch). Optionally, you can also install the power cord tray and use it to manage the power supply cords.

6. Review chassis lifting guidelines as described in Chassis Lifting Guidelines for EX8200 Switches.

Ensure that you have the following parts and tools available to install the switch:

• 24 mounting screws appropriate for your rack
• A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack mounting screws

To install the switch in the rack or cabinet (see Figure 2 and Figure 3):

Caution: If you are installing more than one switch in a rack or cabinet, install the first one at the bottom of the rack. Do not attempt to install a switch manually in an upper position in a rack or cabinet.

1. Ensure that the rack or cabinet is placed in its permanent location and is secured to the building.
2. Position the switch in front of the rack or cabinet, centering it in front of the adjustable mounting brackets. Use a pallet jack if one is available.
3. With one person on each side and one person in the rear, hold the bottom of the chassis and carefully lift it onto the adjustable mounting brackets installed in a four-post rack or onto the power cord tray installed in a two-post rack. See Figure 1.

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

4. In a four-post rack, carefully slide the switch onto the adjustable mounting brackets until the front-mounting brackets attached to the chassis contact the rack rails. The adjustable mounting brackets ensure that the holes in the front-mounting brackets attached to the chassis align with the holes in the rack rails.

   In a two-post rack, carefully slide the switch over the lip of the power cord tray and into the rack. Push the bottom of the chassis so that the front-mounting bracket is flush with the front of the rack.

5. Install a mounting screw into each of the open front-mounting holes aligned with the rack, starting from the bottom.
6. Visually inspect the alignment of the chassis. If the chassis is installed properly in the rack, all the mounting screws on one side of the rack are aligned with the mounting screws on the opposite side and the switch is level.
7. After ensuring that the switch is aligned properly, tighten the screws.
