Installing the Universal Four-Post Rack Kit
Use the following instructions to install 1U and 2U devices in EIA racks that are between L-12.7 to 81.28 cm deep (L-5.0 to 32.0 in.), where L is the chassis depth, using the Universal Four-Post Rack Kit.
- With the port side flush with the front posts.
- With the nonport side flush with the rear posts in a recessed position. A recessed position allows a more gradual bend in the fiber-optic cables connected to the switch and less interference in the aisle at the front of the rack.
| Chassis with port-side side vents | Notes | Chassis depth | Minimum rack depth | Maximum rack depth |
|---|---|---|---|---|
| No | Applicable to port-side and nonport-side flush mounts. | L | L-12.7 cm (L-5 in.) | 81.28 cm (32 in.) |
| Yes | Applicable to port-side flush mounts. | L | L-12.7 cm (L-5 in.) | 81.28 cm (32 in.) |
| Yes | Applicable to nonport-side flush mounts. | L | L | 81.28 cm (32 in.) |
Note that if chassis depth (L) is less than 40.64 cm (16 in.), the chassis will not fit into a rack with a maximum depth of 81.28 cm (32 in.) using the universal four-post rack kit. The maximum rack depth for a chassis less than 40.64 cm (16 in.) is 81.28 cm (32 in.) minus the difference between the chassis depth and 40.64 cm (16 in.). For example, a chassis with a depth (L) of 35.56 cm (14 in.) is 5.08 cm (2 in.) smaller than 40.64 cm (16 in.), so it will install into a rack with a maximum depth of 81.28 cm (32 in.) - 5.08 cm (2 in.) = 76.2 cm (30 in.).
Observe the following when mounting this device:
- Two people are required to install the device in a rack. One person holds the device, while the other screws in the front and rear brackets.
- Before mounting your device, review any specific installation and facility requirements in this Hardware Installation Guide.
