Telesyn 9100 Installation Guide (Installation of Allied Telesyn 9100)
1-41.3.2 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 1-3 Site 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

the minimum space (depth) between the mounting brackets is 485 mm. The extension and rear mounting
brackets allow for more depth if needed.
