Rack Requirements for a QFX3008-I Interconnect Device
You can mount a QFX3008-I Interconnect device on two-post or
four-post racks.
Rack requirements consist of:
- Rack type
- Mounting bracket hole spacing
- Rack size and strength
- Rack connection to the building structure
Table 1 summarizes rack requirements and specifications for a QFX3008-I
Interconnect device.
Table 1: Rack Requirements and Specifications for a QFX3008-I Interconnect
Device
Rack Requirement | Guidelines |
|---|
Rack type and mounting bracket hole spacing | You can mount the device on any two-post or four-post
rack that provides bracket holes or hole patterns spaced at 1 U (1.75
in. or 4.44 cm) increments and that meets the size and strength requirements
specified in this table. A U is the standard rack unit defined in Cabinets,
Racks, Panels, and Associated Equipment (document number
EIA-310–D) published by the Electronics Industry Association. You can stack two QFX3008-I Interconnect devices in a rack that
has at least 42 U. In all cases, the rack must meet the strength requirements
to support the weight of the switch. |
Rack size and strength | - 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 Clearance Requirements for Airflow and Hardware Maintenance for a QFX3008-I Interconnect Device.
|
Rack connection to the building structure | - 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.
