• whether the floor can support the installed weight of the framework
setup, especially when involving a raised floor
• whether there is any other site-specific consideration for installing an
MFA150 framework setup that could also affect the installation of the
switch
An MFA150 system can be anchored beside a Passport 15000 or 20000
without interfering with its telecommunications performance.
CAUTION
Risk of service interruption
An MFA150 power system of ac rectifiers is rated as class
A equipment, therefore it requires an appropriately
controlled environment for your site setup.
For powering one Passport 15000 or 20000 shelf, the Astec identifier
AP5C900FF has two 60-A mid-trip circuit breakers and three Helios rectifiers
25/48 with power factor correction (PFC). For powering two Passport 15000
or 20000 shelves, the Astec identifier AP5C900FG has four 60-A mid-trip
circuit breakers and five Helios rectifiers 25/48 with power factor correction
(PFC). Both kits exclude the recommended No. 6 AWG (13.3mm
armored cable for ac power (R0061445). These hardware configurations are
subject to change, therefore consult with your sales representatives of Nortel
Networks and Astec to determine the most appropriate setup for your
Passport switch and installation site.
For the details of these considerations and the installation of an MFA150, see
the Astec document 167-9021-133 Advanced Power Systems MFA150
Modular Front Access Power System Detailed Installation Guidelines and
Procedures Manual.
Throughout the Passport 15000 and 20000 documents, MFA150 information
has been integrated where necessary. The intent is to coordinate the overall
installation of an MFA150 framework with a Passport that is installed in a
NEBS 2000 frame.
