1-7.1.2 2-TIERED MAIN ENCLOSURE
Guidelines for internal configuration of the 2-Tiered Main Enclosure are listed below:
• Top Tier: Always reserved for the Power Supply/PMU Assembly and Main Controller Board with
keypad/display. The System Enclosure door is designed for the LCD Display to show through
the window at this location. The MCB with keypad/display is designed to fit over the assembly in
a hinged arrangement in the Top Tier.
• Bottom Tier: Typically reserved for two standby batteries (12-AH pair or 17-AH pair) on a tray.
Use of larger capacity battery pairs(greater than 17-AH) requires purchasing the separate Large
Battery Enclosure. An Expansion Card Cage or Power Supply/PMU Assembly may optionally be
located here instead.

1-7.1.3 EXPANSION ENCLOSURES
The FenwalNET 8000-ML system is capable of substantial expansion in its total number of add-on
cards, Power Supply/PMU Assemblies and batteries. The illustrations below demonstrate available
ways of expanding the system. Figure 1-5a shows the large Expansion Enclosure with a power
supply/PMU Assembly and two expansion card cages. Figure 1-5b shows the small Expansion
Enclosure with a Power Supply/PMU Assembly and standby batteries installed. The dimensions of
the small and large expansion enclosures are exactly the same as the dimensions of the 2-tiered and
3-tiered Main Enclosures. The only difference between the Main and Expansion Enclosures is that
the Expansion Enclosure does not include a window in the door.
