intentionally disabled the card. No other LEDs should be on when the “OOS” LED is

lit. The operator can only disable the Controller Card by partially ejecting the Controller

front or rear card. However, the Switch Cards can also be disabled and re-enabled via

the Ethernet and serial interfaces. If a switch card has been disabled via software, it can

be re-enabled via Ethernet or serial control. Or, it can be re-enabled by toggling the

ejector latch.

Controller Card “Status” LED

In addition to the three hot swap LEDS on all Switch and Controller Cards, the Controller

Card has an additional green “Status” LED. This LED indicates the status of the main

processor in the Controller Card. The main processor will begin booting once the green

“OK” LED lights. After a couple of seconds, the processor will finish booting and the

LED will be used to display the status of the processor.

The green “Status” LED will mostly be off if the global back plane switch is off (the global

back plane switch is used to switch all Switch Card’s relays to the Bank B redundant

connector). It will mostly be on if the global back plane switch is set to on (selecting

bank “B”). Be aware that local settings or conditions in the individual switch cards can

override the actual state of the connection.

During operation, the “Status” LED will flicker lightly during Ethernet and RS-232

control to indicate communication is occurring. With Ethernet communication, this

flickering will happen about once a second even when no operations are actively being

commanded. With serial, it will generally flicker only when a command is received.

Regardless of communication occurring, the “Status” LED will flicker every 10 seconds

or so to act as a “heartbeat”, indicating proper operation continues.

Switch Card LED’s

The Switch Card has several additional LED’s. They consist of “Bank A” and “Bank B”

LED’s as well as 3 sets of 4 MADI lock LED’s for the primary Bank A DSP connection,

the redundant Bank B DSP connection and the I/O connection. As with the “Status”

LED on the Controller Front card, these LEDs are lit green “OK” LED when indicating

normal operating conditions. If the “OK” LED is not lit, the card’s integral bypass relays

will release and force a connection between the primary DSP Bank A connector and the

I/O connector.

The “Bank A” and “Bank B” LED’s indicate which DSP bank is currently connected to

the I/O for that card. The 12 individual MADI lock LED’s indicate if there is currently

a valid incoming MADI signal connected to that described connector.
