The S12700 and S12700E series switches can be installed in a standard 19-inch cabinet or rack. Table 5-1 describes the requirements for a cabinet or rack.
Table 5-1 Requirements on the cabinet or rack


Required Height

Required Depth

Other Requirements


≥ 11 U

≥ 600 mm


When a 600-mm deep cabinet is used, ensure that the cabinet doors are single-swing doors.

  • A cabinet with posts in the middle is not recommended because the posts reduce the number of cables allowed in the cabinet or rack.

  • There must be guide rails or a tray in the cabinet to support the chassis.

  • It is recommended that the distance from the front mounting rails to the interior side of the front door (distance a) be 68 mm, 95 mm, 100 mm, or 193 mm. The distance from the card panels with cables connected to the interior side of the front door must be larger than or equal to 110 mm. Otherwise, the number of cables allowed on the switch may be reduced or the front door may be unable to be closed.

≥ 20 U
