Meridian PBX - Routine Maintenance
Please note the following recommendations.
- Look for any damage to the disk(s), or RMD's.
- Check the label to make sure it is the correct disk.
- Handle only the surface of floppy disks.
- Handle only the sides of CD ROM's.
- Keep floppy disks away from strong magnetic fields.
- Store disks or RMD's in a suitable container.
- Backup copies must be made of all PBX room systems: Meridian, Exacom, MAT/OTM, and Voice Mail.
- Backups must be made after any significant programming changes.
Station/Trunk Add, Moves or Changes.
Changes to MAT/OTM Database.
Additions or Deletions in the Voice Mail Program.
If passwords are changed in any system.
- Make multiple copies of all backups. Store backup copies remotely.
- Carefully store software all Key-Codes, and/or Serial Numbers.
The importance of good data backups cannot be stressed enough!
PBX backup procedures should be performed on a regular basis.
- Do Not force the disk or RMD into a drive slot. If there is resistance, remove the disk/RMD and check the orientation (Arrow on the label is up and the rounded corner on the disk is on the bottom).
- Do Not clean the disk drives.
- Do Not Open disk drives, no field maintenance is required.
- Do Not discard any software Key-Codes, or Serial Numbers.
Pedestal Air Filters, 51C, 61C, and 81C:
- Service the air filters once a month. If the filters need to be cleaned more than once a month find out where the dust/dirt is coming from and correct the problem. The switchroom should be a clean office environment.
- Use warm water and a mild detergent to clean the filter.
- After the filter is dry (make sure the filter is thoroughly dry) it can be reinstalled in the pedestal.
- Do Not reinstall a damaged air filter. Discard it and install a new one.
- Do Not use compressed air - it may damage the filter.
- Do Not place a wet filter back into the pedestal. The water will be blown into the PBX causing problems.
- Perform all inspections and tests according to the suppliers instructions.
- Read the Material Safety Data Sheet.
- Perform monthly visual inspections of the batteries and rectifier/charger units.
- Check that the rectifier/charger voltage and current readings are within specifications.
- Do Not place any items on the battery racks.
- Do Not allow moss or corrosion to grow on the terminals.
- Do Not use batteries for any other purpose than to supply power to the Meridian system.
- Lookup system messages. They are listed in "Software Input/Output Guide - System Messages".
- Read and understand all system messages before replacing cards or resetting the system.
- If not sure what a message indicates, contact your service point for guidance.
- Use the correct Load for maintenance and troubleshooting.
Commonly Used Maintenance Programs/Loads:
Prompt Load Action NWS 30 ENABLE/DISABLE/STAT/TEST NPR 32 ENABLE/DISABLE/STAT TRK 32 STAT TDS 34 STAT/TDS loop TRK 36 ENABLE/DISABLE/TEST TRK 41 TEST IOD 37 ENABLE/DISABLE/STAT/TEST CNF 38 ENABLE/DISABLE/STAT/TEST CCED 135 ENABLE/DISABLE/STAT/TEST/SHADOW/SPLIT/SWITCH CIOD 137 DATA/SWAP/SYNC/ENABLE/DISABLE/STAT/TEST
Check Load in "Software Input/Output Guide" manuals for more tests and an explanation of commands.
- Do Not Use the Manual Initialization (MAN INI button) unless a technician has authorized you to. When INI is done call processing will be interrupted. The system then rebuilds call dependent data. Initialization will not correct a hardware problem. The alarm will ultimately come back.
- Do Not Use the Sysload (RLD reload button) unless you are specifically instructed to do so by a technician. A sysload can take from five to 30 minutes during which time no call processing occurs. You ONLY do a Sysload if all call processing has stopped.
- Do Not repeatedly use MAN INI or Sysload to clear problems: this can result in both software and hardware damage.
- Keep it clean!
- Check the A/C and filters on a regular basis.
- Keep all records up to date regarding Adds/Moves/Changes.
- Do Not allow the room to be used as storage area.
