1.3.1 9101 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 9101 shelf. Refer to Table 1-2.

TABLE 1-2Site Requirements for Allied Telesyn 9101

Type	Description
Access (for security reasons)	Installation in a restricted access location is preferred.
System Rear Access	Needed if the ALM IN and ALM OUT is going to be installed (during or
	after initial installation).
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	Connect to a reliable grounded 48VDC source. The branch circuit overcur-
	rent protection must be rated 15 amp maximum, following NEC require-
	ments for permanent office equipment.
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:
	- 17.5 in (442 mm) for all mounting options
	3. Total Shelf Depth: 11.8 in (300 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: 9.5 in (241 mm)
	4. Rack Pitch (Midpoint to Midpoint of each chassis): 25.6 in (650 mm)
