Procedure 9-1
Platform upgrade from a NAC 1 system to a NAC 2 system
Step
Installer's action and system's response
1
Ensure that the MVME167–34 card has been configured correctly. Refer to the
"Hardware installation" chapter, "Configuring the MVME167–34 card" section.
2
Before starting this procedure, follow the instructions for backing up your NAC 1 cus-
tomer data to tape. Refer to NAC 1 Operations (NTP 553-4011-500), "Maintenance
and administration programs" chapter.
Begin by first shutting down the software of the NAC 1 system.
3
Use the ACD-NAC Maintenance and Administration menu and choose option b,
Backup and Restore Utilities .
Note: ACD-NAC backup should be made on a 150 Mbyte (megabyte) tape.
4
From the Backup and Restore Utilities submenu, choose option b again, "Backup
Customer Data to Tape" to save the system's database. This ensures that all current
data is backed up.
This procedure uses large cartridge tapes. Care must be taken to avoid damaging
the tape, as its fragility can result in tape errors during the installation procedure.
Keep tapes away from excessive heat or electromagnetic radiation.
5
Remove the front and rear panels of the Application Equipment Module (AEM).
6
Remove the AEM backplate to access the NAC application module transition cards.
7
Make sure the AM is powered off. The power switches for each module are located
at the left side of the AEM.
8
Find the label "SCSI INTERFACE" at the lower right side of the MVME712M transi-
tion card located at the rear of the AM. Below the label "SCSI INTERFACE" is the
external SCSI port with a SCSI terminator-connector attached to it.
If your NAC module is in the second module of the AEM, go to Step 11.
If your NAC module is in the first module of the AEM, go to Step 9.
9
Remove the power supply faceplate located at the back of the module on the right
side.
10
Put the SCSI cable through the power supply hole and behind the backpanel.
