Juniper EX8216 Mounting Instructions

Mounting an EX8216 Switch on a Rack or Cabinet

The EX8216 switch ships installed with front-mounting brackets on the chassis for
mounting the switch on a 19-in. equipment rack or cabinet. (The remainder of this
topic uses rack" to mean 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 21 U without the optional power cord tray
and 22 U with the optional power cord tray. Installation in a two-post rack is not
supported. You can mount two switches on a 42 U four-post rack provided that the
rack meets the strength requirements to support the combined weight of the switches.
WARNING: Because of the switch's size and weight, we require the use of a
mechanical lift to install the switch.
CAUTION: If you are installing more than one switch in a rack, install the first switch
at the bottom of the rack.
CAUTION: Do not install line cards in the chassis until after you mount the chassis
securely on a rack.
