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
TABLE 1-2 Site 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. 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) |
