IEC power supply connectors. For more information about the
twin power supplies, see 3.2.2 Power supplies.
Spare slots for interface card rear connector panels. All front
installed interface cards require a corresponding rear connector
panel. Blank panels can be installed to unused slots.
The Eclipse HX-Median has 7 slots available for interface cards. For
more information, see 3.3 Interface cards.
MVX-A16 analog interface card rear connector panel.
An MVX-A16 rear connector panel has 16 RJ-45 connectors for
connecting intercom panels and interfaces. For more information
about MVX-A16 cards, see 3.3.1 MVX-A16 analog port card.
CPU card rear panel. The CPU card rear panel houses connectors
for an external PC, network, interfaces, alarms and other matrices.
Up to 2 CPU cards can be installed to the matrix, but only one rear-
panel CPU card is required. Whichever of the two front-installed
CPU cards is acting as master will work in conjunction with this
card. For more information, see
3.2.4 CPU card.
Interface module slots. The Eclipse HX-Median has 8 built-in
interface module slots. For more information, see 3.4 Interface
modules.

3.2.2 Power supplies
The Eclipse HX-Median matrix has two Euro Cassette power supply units
that can be easily installed or removed as needed. One power supply unit can
power an entire matrix. The second unit provides a backup in case of failure or
damage to the first unit.
In addition, the two supplies have separate IEC connectors to AC mains, and are
designed for completely automatic and transparent changeover between supplies
in the event of a power outage in one of the AC mains circuits.
An over-temperature sensor is connected to both an audible failure alarm and a
warning light, allowing the system operator to diagnose and correct any power
anomalies while the system remains operational.
Eclipse HX-Median matrices may be fitted with XP (part 740101Z) or Power-
One (part 720379Z) power supply units, depending on the date of
manufacture.
The different types of power supply units must not be mixed in
an HX-Median matrix; if one of the pair of power supplies is
replaced it must be replaced with the same type of power supply
unit. If this is not possible both power supplies must be replaced
with power supply units of the same type.
