Guidelines
Ensure that the rack is a 19-in. rack as defined in Cabinets, Racks, Panels, and
Associated Equipment (document number EIA-310–D) published by the Electronics
Industry Association.
Ensure that the rack rails are spaced widely enough to accommodate the QFX3008-I
Interconnect device external dimensions of 17.3 in. (43.9 cm) width. The outer edges
of the front-mounting brackets extend the width to 19 in. (48.3 cm).
The QFX3008-I Interconnect device height of 36.65 in. (93.09 cm) is approximately
21 U.
The rack must be strong enough to support the weight of the fully configured device.
A fully configured QFX3008-I Interconnect device weighs approximately 650 lb
(295 kg). If you stack two fully configured devices in one rack, that rack must support
up to 1300 lb (590 kg).
Ensure that the spacing of rails and adjacent racks allows for the proper clearance
around the switch and rack as specified in
Hardware Maintenance for a QFX3008-I Interconnect Device" on page
Secure the rack to the building structure.
If earthquakes are a possibility in your geographical area, secure the rack to the
floor.
Secure the rack to the ceiling brackets as well as wall or floor brackets for maximum
stability.
