Meridian PBX - Routine Maintenance

Vendor Software:

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.
Eg: Station/Trunk/Voice-Mail Adds, Moves or Changes, changes to MAT/OTM Database, password changes in any system.
The importance of good backups cannot be stressed enough! Backup procedures should be performed regularly.
Make multiple copies of all backups. Store backup copies remotely.
Carefully store software all Key-Codes, and software licenses.

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).
Remove a disk (or RMD) when the activity light is flashing.
Clean the disk drives.
Open disk drives, no field maintenance is required.
Discard any software Key-Codes, or Serial Numbers.

Service Air Filters (and MG1010 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.

Reinstall a damaged air filter. Discard it and install a new one.
Use compressed air - it may damage the filter.
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 supplier's 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.

Place any items on the battery racks.
Allow moss or corrosion to grow on the terminals.
Use batteries for any other purpose than to supply power to the Meridian system.

ALWAYS lookup system messages (listed in: Software Input/Output Guide - System Messages).
Read and understand all system messages before replacing cards or resetting the system.
If you're not sure what a message indicates, contact your service point for guidance.
Use the correct Load for maintenance and troubleshooting.

Load	Prompt	Action
30	NWS	ENABLE/DISABLE/STAT/TEST
32	NPR	ENABLE/DISABLE/STAT
32	TRK	STAT
34	TDS	STAT/TDS loop
36	TRK	ENABLE/DISABLE/TEST
41	TRK	TEST
37	IOD	ENABLE/DISABLE/STAT/TEST
38	CNF	ENABLE/DISABLE/STAT/TEST
135	CCED	ENABLE/DISABLE/STAT/TEST/SHADOW/SPLIT/SWITCH
137	CIOD	DATA/SWAP/SYNC/ENABLE/DISABLE/STAT/TEST

Check Software Input/Output Guide manuals for more tests and an explanation of commands.

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.
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.
repeatedly use MAN INI or Sysload to clear problems: this can result in both software and hardware damage.
