Mounting a QFX3600 or QFX3600-I Device on Two Posts in a Rack or
Cabinet
You can mid-mount a QFX3600 or QFX3600-I device on two posts of a 19-in. rack or cabinet by using
the mounting brackets provided with the device. (The remainder of this topic uses “rack” to mean “rack
or cabinet.”)
You can also mount the device on four posts of a four-post rack by using the mounting brackets provided
with the device. See “Mounting a QFX3600 or QFX3600-I Device on Four Posts in a Rack or Cabinet” on
page 303 .
The holes in the mounting brackets are placed at 1 U (1.75 in., or 4.45 cm.) apart so that the device can
be mounted in any rack that provides holes spaced at that distance.
