Installing the Cable Management System on a QFX3008-I Interconnect Device on
page 429
The QFX3008-I Interconnect device ships installed with front-mounting brackets and
center-mounting brackets on the chassis for mounting the device on a 19-in. equipment
rack or cabinet. (The remainder of this topic uses "rack" to mean "rack or cabinet.") The
chassis also comes with mounting shelves and brackets to support it in the rack.
Because of the chassis size and weight, we require using a mechanical lift to install the
device.
CAUTION: Before mounting the device in a rack, have a qualified technician
verify that the rack is strong enough to support the device's weight and is
adequately supported at the installation site.
NOTE: In a rack, the chassis occupies 21 U. You can mount two devices on a
42 U rack provided that the racks meet the strength requirements to support
the combined weight of the devices. If you are mounting two devices on a
rack, mount the first device on the bottom of the rack.
Before mounting a QFX3008-I Interconnect device in a rack:
Verify that the site meets the requirements described in
