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.

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.
