Complete Hardware Guide for EX8208 Ethernet Switches

NOTE: You must provide mounting screws that are appropriate for your rack to front-mount the chassis on a rack or a cabinet.

For two-post rack installation, you need 28 screws: 24 screws to attach the front-mounting bracket “ears” that come installed on the chassis to the front of the rack and 4 screws to install the power cord tray. (The power cord tray is mandatory for two-post rack installation.)

For four-post rack installation, you need either 40 or 44 screws: 24 screws to attach the front-mounting bracket “ears” that come installed on the chassis to the front of the rack, 16 screws to attach the adjustable mounting brackets to the rack, and 4 screws if you install the optional power cord tray.

Installing Adjustable Mounting Brackets in a Rack or Cabinet for an EX8200 Switch

To mount the switch on a four-post rack or cabinet, you must first install the adjustable mounting brackets in the rack or cabinet. (The remainder of this topic uses “rack” to mean “rack or cabinet.”) The EX8200 switch comes with a four-piece set of adjustable mounting brackets that supports the chassis in the rack.

NOTE: The adjustable mounting brackets are not for installation in two-post racks.

The four adjustable mounting bracket pieces are:

•1 left front adjustable mounting bracket. The bracket is labeled “LEFT FRONT” on the side of the bracket that faces the interior of the rack, near the holes for attaching the bracket to the rack.

•1 right front adjustable mounting bracket. The bracket is labeled “RIGHT FRONT” on the side of the bracket that faces the interior of the rack, near the holes for attaching the bracket to the rack.

•2 rear adjustable mounting brackets. These brackets are labeled “REAR” on the side of the bracket that faces the interior of the rack, near the holes for attaching the bracket to the rack. The rear brackets are interchangeable; you can use either of the rear brackets with the right or left front adjustable mounting bracket.

Ensure that you have the following parts and tools available to install the adjustable mounting brackets:

•A Phillips (+) screwdriver, number 1, 2, or 3, depending on the size of your rack mounting screws

•A Phillips (+) screwdriver, number 2 to install the screws that connect the rear and front mounting brackets
