Mounting an EX3200 or EX4200 Switch on Four Posts in a Rack or Cabinet
You can mount an EX3200 or EX4200 switch on four posts of a 19-in. rack or cabinet by
using the separately orderable four-post rack-mount kit. (The remainder of this topic
uses “rack” to mean “rack or cabinet.”)
You can mount the switch on two posts in either a two-post rack or a four-post rack by
using the mounting brackets provided with the switch. See “Mounting an EX3200 or
EX4200 Switch on Two Posts in a Rack or Cabinet” on page 122.
