Problems with Mira Server in General
Symptom
Solution
Video output is not synchronized with downstream devices.
Have you connected bi-level analog reference to reference input?
Connect bi-level reference to the input reference connector—please
refer to item (I) on page 20.
I cannot record external timecode.
Have you connected analog timecode to the LTC IN on the chassis rear?
Connect analog timecode signal to the LTC IN connector.
Ensure the timecode signal is 1V peak-to-peak minimum.
How do I record more than just two tracks of audio?
Mira comes standard with 8-track embedded audio per video channel as a
standard feature. To record more than two-track audio, you must enable
the selection in Mira Engineering Setup utility, under the “
Audio
” tab. See
page 208 for more information.
I hear a beeping sound from inside the main server chassis.
This could be either a power supply problem or a media disk drive
problem.
Check to see if two power cords are connected to the AC input on
both power supplies; if only one power cord is connected, then the
internal alarm will sound. The only way to silence the alarm is to either
connect AC power to both modules; or remove the module without
power, and operate with just one power module (not recommended).
If the two power cords are connected to the two modules of the power
supply, and you’re sure there is full power on both power cords, then
check the small l.e.d. on each of the two power supply modules (from
the chassis rear); these lights should be solid green. If either light is
blinking, or has changed to yellow or red, then you may have a power
module failure. Remove the suspect module immediately—the alarm
should then mute. Please telephone Abekas technical support for
assistance: (+1-650-470-0905 in the PST time zone of United States).
If the power supply checks okay, then remove the plastic front panel
cover from the front of the Mira Server; check the row of blue lamps
above the two disk drive bays. All 12 of these lights should be OFF;
are any of these lights ON or blinking? If yes, then there may be a
failed media disk drive. Please telephone Abekas technical support for
assistance: (+1-650-470-0905 in the PST time zone of United States).
Since the media disk array is RAID-6 parity-protected, all recorded
media are protected, even with up to two failed media disk drives. You
may experience slight reduction in video playback performance in
some cases when one or two media disk drives have failed—for
example, jog operation may appear less smooth. However, media
record operations will be unaffected by one or two media disk drive
failures.
It is strongly recommended to replace a failed media disk drive as
soon as possible. This is especially true if two media disk drives have
failed—if a third media disk drive were to then fail, then all recorded
media on Mira will be forever destroyed!
