Operational reliability —

The Matrix 12800 can support round-the-clock operation

in mission-critical applications, using a combination of self-diagnosis, hot-

swappable components, and optional redundant components.

Advanced computer-aided diagnostics — The Matrix 12800 performs self

diagnostics, 24 hours a day, of the I/O cards, primary and redundant power

supply voltages, controller cards, cooling status, and the overall functional

status of the matrix. The status can be monitored off-site for unmanned

applications via the Ethernet or RS-232/RS-422 communications ports.

Dual redundant, hot swappable controller cards — The primary and

redundant controller cards are internally mounted. The primary and

redundant controller cards can each initiate configuration changes or other

matrix switcher operations. Each card has an RS-232/RS-422 port for

connection of a PC or control system. Redundant controllers mean zero

downtime for the system. There is no loss of functionality should one of the

controller cards fail. A failed controller card is easily replaceable through the

front door with no tools required. Hot swappable controllers allow the user to

replace either at any time — without powering down the matrix.

Dual redundant, hot swappable power supplies — The internally mounted

primary and redundant power supplies are configured to automatically switch

over from a primary supply to a hot redundant supply in the case of a failure.

The complete power circuit, from the plug, through the power supplies, to

the insertion of the power onto the power distribution plane, is separate

and redundant (figure 1-3). If the installation includes uninterruptible or

completely separate power sources, the switcher remains powered up through

any power interruption short of a simultaneous loss of power on both power

sources.

The ready hot redundant power supplies mean zero downtime for the system

and no loss of functionality should one of the primary supplies fail. Should

a primary power supply fail, the redundant power supply immediately

assumes the load of the failed primary supply. A failed power supply is easily

replaceable through the front door at any time — without powering down the

matrix, and with no tools required.
