INSTALLATION
2. Installation
The MP3 is a 3RU chassis and comes pre-assembled and ready to mount to any existing 19” rack cabinet hub system using
10/32” rack screws.
NOTE: This equipment is intended for installation in a RESTRICTED ACCESS LOCATION only.
NOTE: Not for use in a computer room as dened in the Standard for Protection of Electronic Computer/Data Processing
Equipment, ANSI/NFPA 75.
Rack Mounting Precautions
a) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature
of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing
the equipment in an environment compatible with the maximum ambient temperature (35ºC) specied by the
manufacturer.
b) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of airow required for
safe operation of the equipment is not compromised.
c) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
d) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit
and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when addressing this concern.
e) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention should
be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).”
2.1. Module Installation Into the MP3 Chassis
All MAXNET II active and passive chassis have 24 grooves that act as guide slots for the active and passive modules.
Passive modules and the DC Logic Switch can be inserted into any of the 24 slots. Active modules must be inserted into the
odd number slots indicated by the white markers on the bottom rail of the chassis. These odd numbered slots are the
only slots that will allow an active module to be connected to the active chassis backplane to receive power and allow monitor
and control of the module. To insert a module, align the module guide rails to the chassis guide slots and then gently slide
the module into a locked position (the module should be ush against the top and bottom rail of the chassis). No mounting
hardware is required. To remove a module, grab the front handle on the module and gently lift and pull back the module until
it is clear of the chassis guide rails.
NOTE: When installing the MPAC or MPDC Power Supply, the GND bonding terminal #1 on the back of the MPAC or
MPDC Power Supply shall be connected to the chassis ground lug.
2.2. Powering the Active MP3 Chassis
The MP3 active chassis can be powered by power supply modules (MPAC-110, MPAC-220 or MPDC) installed in one of the
slots of the chassis, or by connecting power directly to one or both of the terminal block inputs on the rear of the chassis. Both
connections are not necessary unless redundancy is required. If the source of 24 VDC is not an MPXX power supply, the line
should be fused at a minimum with a 10 Amp slo-blo fuse. A disconnect device is required between the 24 VDC supply and
the Chassis remote power terminals.
