1.3.2 9102/9103 Site Requirements

The Allied Telesyn 9101 is installed in a environment that is affected by the existing installed equipment and the specific requirements of the Allied Telesyn 9102/9103 shelf. Refer to Table 1-3.

TABLE 1-3Site Requirements for Allied Telesyn 9102 / 9103

Type	Description
Number of people	Two people are required when mounting the shelf.
Access (for security reasons)	Installation in a restricted access location is preferred.
System Rear Access	Required, for power supply cord and grounding access, and to install /
	remove power converters.
Installation Placement	Placement: follow local cabling setup (from above, below, etc.)
	Care should be taken not to compromise the stability of the rack by the
	installation of this equipment.
	Note: Due to weight limitations and the size of bundled cabling, 21 units can
	physically be installed in a single 7 ft. telecom rack. However, the user
	should verify that the floor loading for the rack, with the required number of
	units installed, does not exceed the floor loading standard for the region or
	country where the 9101(s) is being installed. 9101 installations inside the
	U.S. would follow the Bellcore (Telcordia) floor loading standard of 114.7
	lb. per square foot. See the Allied Telesyn Component Specification for the
	NEBS specification.
Power Supply	120/220V, 50/60Hz
Spacing	Refer to Figure 1-3for installation spacing and numbers:
	1. Mounting Width Aperture: 19.7 in (500 mm) min.
	2. Aperture between mounting flanges:
	- 17.4 in (442 mm) for all mounting options
	3. Total Shelf Depth: 23.8 in (605 mm):
		a. Door or cover: .4 in (10 mm) (Front and Back)
		b. In front of Reference Plane for equipment (i.e. subracks): 1.6 in (41
	mm)
		c. Behind Reference Plane:21.5 in (545 mm)a
	4. Rack Pitch (Midpoint to Midpoint of each chassis): 25.6 in (650 mm)

a.For front mount, the minimum space (depth) between the mounting brackets is 545 mm. For mid mount, the minimum space (depth) between the mounting brackets is 485 mm. The extension and rear mounting brackets allow for more depth if needed.
