Chassis
Metal guides on the inside of the chassis align with the plastic guide rail on top of the
modules, allowing the modules to slide into the chassis easily. All RF and optical connections
are made directly to the application modules installed in the chassis. Modules plug into the
backplane interconnection circuit board (with DC bus and SPI bus), which routes DC voltages
and communications signals between modules.
Each chassis requires one power supply and accepts a second for load sharing and
redundancy. A management module provides an interface between the management system
and the CHP Max5000 chassis. Rear-mounted
Shelf Interconnect
jacks (RJ-14) permit
daisy-chaining of an entire rack of CHP Max5000 chassis for remote monitoring. A terminal
block provides external alarm relay for such functions as an autodialer.
The original CHP Max5000 recessed chassis (P/N CHP-CHASSIS-R-19) and its replacements
(P/N CHP-CHASSIS-R-19Q and CHP-CHASSIS-R-19S) are no longer available for purchase.
Table 3.1 lists the mechanical specifications of the chassis..
Tools and Materials
Table 3.2 describes the tools, equipment, and materials that may be required to install,
maintain, and test the chassis. Persons performing the procedures in this manual are
expected to be familiar with the proper and safe use of these tools. Tools or equipment with
equivalent or superior specifications may be substituted for those listed.
