Rack Mount the NCS-57C3-MOD Chassis in a 4-Post Rack using Sliders

This section describes how to install the Cisco NCS 57C3-MOD chassis on the 4-post rack, using sliders. The
sliders are used to install the chassis on a 4-post rack. Sliders are used to access the fan trays in the chassis
easily during maintenance.

To install the NCS 57C3-MOD chassis in a 4-post rack without using the sliders, use the 2-post rack mount
procedure (

NC55-2RU-ACC-SL1

—Designed for custom-made cabinets that are 476 mm wide (min. 650 x650

mm), or for cabinets with equivalent specifications. This slider is attached directly to the chassis.

Rack Requirements to Install NC55-2RU-ACC-SL1:

• 4-post rack

• 476 cm wide center to center rail mounting.

• The width between the front rack-mounting rails must be at least 17.75 inches (45.0 cm)

• The minimum spacing for the bend radius for fiber-optic cables should have the front-mounting

rails of the cabinet offset from the front door by a minimum of 4.7 inches (12.0 cm).

• The minimum spacing between the front-mounting rails of the cabinet to the inner surface of the

front door shall be min. 5.8 inches (14.7 cm). Depend on cabinet ambient thermal set-point this
distance can change.

• The distance between the outside face of the front mounting rail and the outside face of the

back-mounting rail should be 16.0 to 19.9 inches (40.7to 50.5 cm) to allow for rear-bracket
installation.

NC55-2RU-ACC-SL2

—Designed for 19-inch (min. 650 x650 mm) EIA cabinet standard 4-post rack.

This slider uses a tray (PID: NC57C3-ACC-SL-TR) and the chassis is mounted to the tray.

Rack Requirements to Install NC55-2RU-ACC-SL2:

• Standard 19-inch (48.3 cm) (four-post EIA cabinet, with mounting rails that conform to English

universal hole spacing per section 1 of ANSI/EIA-310-D-1992.)

• The width between the front rack-mounting rails must be at least 17.75 inches (45.0 cm.)

• The minimum spacing between the front-mounting rails of the cabinet to the inner surface of the

front door shall be min. 5.8 inches (14.7 cm). Depending on the cabinet ambient thermal set-point
this minimum distance can change.

• The minimum spacing for the bend radius for fiber-optic cables should have the front-mounting

rails of the cabinet offset from the front door by a minimum of 4.7 inches (12.0 cm).

• The distance between the outside face of the front mounting rail and the outside face of the

back-mounting rail should be 16.5 to 19 inches (41.9 to 48.26 cm) to allow for rear-bracket
installation.

The slider assembly consists of three parts:

• Inner Slider Member
