3.3.1 Chassis and assembly
The matrix chassis is a metal rectangular box which measures three rack units
(6RU) high and 19-inches wide (13.45 cm x 48.3 cm). The Eclipse HX-Delta has:
• 2 CPU cards.
• Slots for 4 interface cards, and 3 interface modules.
• 2 12V external power supplies (for redundancy).
• 2 internal cooling fans (for redundancy).
• Rear to front Ethernet / panel feed through.
• Front handles for easier removal from the rack.
RJ-45 and fiber-optic connectors are located on removable plates on the rear of
the chassis. These connect the interface cards and modules to user panels, four-
wire audio equipment, wireless equipment, and other intercom devices.
