PRODUCT DESCRIPTION
1. Product Description
The MP3 chassis is a 3RU design that comes in both a passive and active conguration. Both congurations include options
for dual cable management bars and a large cable management tray as well as user congurable horizontal and vertical
cable management systems. The MP3 active chassis also include a ber management tray that can be congured into two
positions.
The passive and active chassis’ can accommodate up to 24 single-width passive modules (DC Logic A/B RF Switch; 2,
4, 8, dual 4-way and triple 2-way splitters\combiners; DC & triple DCs) or up to 12 dual-width modules (16-way splitter\
combiners).
The active chassis can accommodate all the modules that a passive chassis can, but also up to 12 dual-width active modules
(amplier, power supply, optical receiver\transmitter, RF Switch).
The active chassis comes with a +24 VDC power interface backplane/rail and a removable communications module that
draws power from the rail. This communications module can be removed without affecting the operation of the modules in the
chassis by removing the two Phillips screws on either side that fasten it to the chassis. All active modules are hot-swappable.
Power is supplied to the backplane by installing an MPAC or MPDC power supply into one of the chassis slots or by remotely
powering the chassis from an external 24 VDC supply. The MP3 active chassis is equipped with an HMS compliant SNMP
management system. An RJ-45 port is used for both set-up and status monitoring. No custom software is required.

Provided that the chassis is not being solely powered via the terminal block on the comm module, there would simply be no alarms and no remote
adjustment of parameters. The modules would continue to run with the last set values.
2
It is not recommended to hot swap a power supply module into a full chassis if there is no other power supply present. The current surge to supply a
full rack of active modules would be stressful on the electrical contacts during mating and may reduce the lifespan of the chassis and power supply. It
is recommended that you install the power supply rst, then apply AC or DC input to the power supply connector.
