Mounting an EX8208 Switch on a Rack or Cabinet

The EX8208 switch ships installed with front-mounting brackets on the chassis for mounting the switch
on a 19-in. equipment rack or cabinet. The switch also comes with adjustable mounting brackets to support
it in the rack.
In a four-post rack, the switch consumes 14 U without the optional power cord tray and 15 U with the
optional power cord tray. In a two-post rack, the power cord tray is mandatory. The switch with the power
cord tray consumes 15 U. You can mount up to three switches on a 42 U four-post rack or on a 45 U
two-post rack provided that the racks meet the strength requirements to support the combined weight
of the switches.
NOTE: If you are mounting multiple switches on a rack or cabinet, mount a switch on the bottom
of the rack or cabinet first and then mount the rest of the switches from bottom to top.
