FRONT PANEL STATUS LED INFORMATION
LED Description Display
PSU Power Supply Status
ON SOLID GREEN —Normal, indicates both PSUs are functioning.
OFF
—One or both PSUs is faulty or has no AC input.
FAN Fan Status
OFF
—Normal, internal fan is functioning.
FLASHING RED
—Fan is faulty.
Port 1/2 Con Hydra port Connection
ON SOLID YELLOW
—Normal, indicates a valid Hydra2 port connection is made.
OFF —Hydra2 port connection is not valid.
Port 1/2 Act Hydra Port Activity
FLASHING GREEN
—Under normal operation, once the connection is
established, this LED should be flashing in a regular pattern, approx 10 times per
second.
OFF
—No activity on the Hydra link.
Status 1 Unit Booted & Initialized
ON SOLID GREEN —Normal, indicates the unit has booted and the Hydra2 ports
are enabled.
OFF —Unit has failed to boot.
Status 2 Primary Router Heartbeat
FLASHING GREEN*
—Normal, should flash approx 2 times per second. Indicates
a valid link between port 1 and a Hydra2 primary router.
OFF or ON SOLID
—Failed link between port 1 and Hydra2 primary router.
Status 3 Secondary Router Heartbeat
FLASHING GREEN*
—Normal, should flash approx 2 times per second. Indicates
a valid link between port 2 and a Hydra2 secondary router.
OFF or ON SOLID
—Failed link between port 2 and Hydra2 secondary router.
Status 4 No Function**
Status 5 Primary Control Data
ON SOLID RED
—Normal, indicates primary control data connections are
established between port 1 and a Hydra2 primary router.
OFF
—Primary control data has failed / cannot be established.
Status 6 Secondary Control Data
ON SOLID RED
—Normal, indicates secondary control data connections are
established between port 2 and a Hydra2 secondary router.
OFF
—Secondary control data has failed / cannot be established.
Status 7 Primary Audio / Sync active
ON SOLID RED***
—Normal, audio and sync input to the unit active from port 1.
OFF
—Unit is not actively receiving audio / sync via port 1.
Status 8 Secondary Audio / Sync active
OFF
—Normal, unit is not using audio / sync input from port 2 (secondary /
backup) .
ON SOLID RED***
—Unit is using audio and sync from port 2, indicates a problem
with the primary path.
• Primary and secondary heartbeat LEDs are often seen to flash synchronously—together, in time with each other, however,
this is not important. As long as each LED is flashing approximately twice per second, both ports have an active and reliable
comms path with a Hydra router. Under normal boot-up, from power on or reset, the heartbeats will start off in sync with each
other. Over time, slight differences in timing between them will lead to the heartbeats being out of sync with each other - this
is normal operation. Heartbeats will be out of sync with each other from the start if the system is already booted and the Hydra
connections are physically plugged in one at a time.
** The function of status LEDs can be subject to change with software versions. Under some software versions, status LED 4
may light to indicate a PSU issue during bootup and is primarily used by Calrec Engineers for troubleshooting rather than for
guidance during normal operation.
*** Status LEDs 7 and 8 may be lit at the same time if an I/O box is receiving signals on its secondary connection.
