Installing the Power Cord Tray in a Rack or Cabinet for an EX8200 Switch

The power cord tray is supplied with all EX8200 switches. The power cord tray is optional for four-post rack or cabinet installation but mandatory for a two-post rack or cabinet installation. (The remainder of this topic uses “rack” to mean “rack or cabinet.”) To mount an EX8208 switch in a two-post rack, you must install the power cord tray in the rack before installing the switch.

Note: The EX8216 switch can be installed only in a four-post rack. Installation in a two-post rack is not supported.

The power cord tray provides support for the front of the EX8208 chassis during installation of the switch in a two-post rack. The front edge of the chassis rests on the upper edge (lip) of the power cord tray.

The power cord tray provides a place to organize and tie down the power cords for the power supplies.

The power cord tray uses 1 U of rack space, so the total space occupied by an EX8208 switch chassis and power cord tray is 15 U, and the total space occupied by an EX8216 switch chassis and power cord tray is 22 U.

Ensure that you have the following tools and parts available to install the power cord tray:

• A Phillips (+) screwdriver, number 1, 2, or 3, depending on the size of your rack mounting screws
• 4 mounting screws appropriate for your rack to attach the power cord tray to the rack

To install the power cord tray (see Figure 1 and Figure 2):

1. Remove the power cord tray from the accessory box.
2. Decide where to position the switch in the rack. If the rack is empty, choose the lowest possible location. See Rack Requirements for an EX8208 Switch, Rack Requirements for an EX8216 Switch, Cabinet Requirements and Specifications for an EX8208 Switch and Cabinet Requirements and Specifications for an EX8216 Switch.

   Note: To mount an EX8208 switch on a two-post rack, you must install the power cord tray in the rack before installing the switch. See Figure 2. Installation of an EX8216 switch in a two-post rack is not supported.

3. Position the power cord tray in the rack space immediately below the position in which you want to install the switch (in a two-post rack) or where the switch is installed (in a four-post rack) (see Figure 1). Line up the screw holes of the power cord tray with the holes in the rack. Use 4 mounting screws appropriate for your rack to attach the power cord tray to the rack.
