Plan For The Use Of An Equivalent Mounting Apparatus - Nortel Passport 15000 Preparation Manual

Plan for the use of an equivalent mounting apparatus

The Passport 15000 or 20000 shelf and the NEBS 2000 frame comply to
applicable sections of the Network Equipment Building System (NEBS)
standard. When the Passport 15000 or 20000 shelf is installed in a mounting
apparatus other than the NEBS 2000 frame, additional frame level testing
may be required to ensure compliance.
NEBS compliance of the shelf and frame combination is your responsibility.
Nortel Networks may not offer the Passport 15000 or 20000 shelf in the frame
or cabinet you have selected.
When installing a Passport 15000 or 20000 into a mounting apparatus other
than the NEBS 2000 frame, the hardware is provided in a shelf kit.
The shelf kit, designed to fit a Passport 15000 or 20000 into a 23-inch EIA
rack, complies with Seismic Zone 2 requirements when installed in the
bottom of the frame. The preferred installation is into a rack with no doors,
however, installation is possible in a cabinet with solid or perforated doors.
See 241-1501-240 Passport 15000, 20000 Hardware Installation,
Maintenance and Upgrade for installation information.
