•24 mounting screws appropriate for your rack

To mount the EX8208 switch on a rack or cabinet (see Figure 46 on page 140 and Figure

47 on page 140):

1.In a four-post rack or cabinet, install the adjustable mounting brackets at the desired position (see “Installing Adjustable Mounting Brackets in a Rack or Cabinet for an EX8200 Switch” on page 132).

In a two-post rack or cabinet, install the power cord tray (see “Installing the Power Cord Tray in a Rack or Cabinet for an EX8200 Switch” on page 135). The power cord tray is optional for four-post rack installation.

2.Lift the chassis into the rack using a mechanical lift. For instructions on how to install the chassis using a mechanical lift, see “Mounting an EX8208 Switch on a Rack or Cabinet Using a Mechanical Lift” on page 141.

In a four-post rack, place the chassis on the adjustable mounting brackets. In a two-post rack, place the front edge of the chassis on the lip of the power cord tray with at least three people supporting the rear of the chassis until you can bolt the chassis into the rack.

If a mechanical lift is not available, remove all components and ensure that at least three people are available to lift the empty chassis into the rack. For instructions on how to install the chassis without using a mechanical lift, see “Mounting an EX8208 Switch on a Rack or Cabinet Without Using a Mechanical Lift” on page 143.

3.Insert 24 mounting screws appropriate for your rack (not provided) into the aligned holes. Use the appropriate Phillips (+) screwdriver to tighten the screws to the rack or cabinet rail.
