Brought up during OS initialization only if the system determines
that one or more of the 80386SX, faceplate and alarm controller,
or alarm board FPROMs must be reprogrammed.
Reprogramming is done automatically.
!WARNING:
The system should never be shut down during the
reprogramming sequence.  The MFB will have to be sent
back to the factory if programming is not allowed to
complete.

ASAI-XASAI-Ethernet State  Ð Displayed when the DEFINITY LAN
Gateway software is fully initialized and providing service, or

Shutdown Statesbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
E_SHUTError Shutdown Ð Flashes whenever a critical error condition is
encountered and the system is shutting down. Once the disk is
spun down, the display becomes steadily lit. Flashware
continues to execute. Can also be entered when:
Board tests have failed and the red LED is lit.
Flashware or software has failed to initialize and has shut
down.
A maintenance shutdown was directed and an operational
error occurs. For instance, the Faceplate and Alarm Panel
(FAC) timed out on the transition of the MFB to the
M_SHUT state.
On a running system, maintenance software detects a
condition requiring an error shutdown.
When in this state, the system can be powered down and
removed from the switch carrier for repair.
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
M_SHUTMaintenance Shutdown Ð Flashes when a technician has
directed Maintenance shutdown either by pressing the
BOOT/SHUTDOWN button, or through the SYSTEM
SHUTDOWN command on a maintenance terminal. Flashware
executes and the disk is spun down. Once the system is
completely shut down, the display becomes steadily lit.
When in this state, the system can be powered down and
removed from the switch carrier for repair.
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
S_SHUTShows only if the interboard bus cable is disconnected.
Reconnecting the cable will bring the system back to the OA&M
or ASAI-E state.

Figure 4-3, System Initialization and Shutdown Flow, shows the steps the
DEFINITY LAN Gateway system automatically takes from a dead state to full
operation. It also shows the states that can be entered whenever errors occur, or
when the technician manually changes states using the faceplate panel or with
the maintenance screens located in Chapter 3.  Note that the states are shown

Maintenance Connectionsbbbbbbbbbbbbbbb
Common types of console terminals are used for both switch and local DEFINITY
LAN Gateway maintenance, allowing the same baud rates and parity to be used.
Although a local maintenance terminal is optional, it does need to be available for
installation and troubleshooting.  A remote maintenance terminal may also be
used.
Figure 4-4, Available Terminal Connections to a DEFINITY LAN Gateway
System, summarizes the terminal configurations available with the system.

Maintenance Login Procedurebbbbbbbbbbbbbbb
This is not a procedure. Please supply. If you cannot log in, first check
terminal power, connections, settings, and modem speed if you are connected
via a modem. If the modem appears to be locked up, type * @ ; this may fix the
remote access problem. If you still cannot reach the DEFINITY LAN Gateway
system, call the switch administrator. Is the switch working? Can the
administrator call into the system? A technician may have to be dispatched to the
site.
Maintenance Proceduresbbbbbbbb
Replacing the Circuit Packsbbbbbbbbbbbbbbb
Refer to Figure 4-5 and follow the steps listed below to replace the MFB or Alarm
Board.

!WARNING:
Static electricity can be destructive to system parts.  Use an anti-static wrist
strap whenever removing or installing a DEFINITY AUDIX system. Also use
an anti-static mat when taking the system apart to replace circuit packs or
storage devices.
1. Ensure that the customer knows you will be powering down the system
and disrupting service.
2. If it is not already shut down, bring the system to the MSHUT state.
(From the Main Menu, select Maintenance, Reset System, and then
Shutdown.)

3. Unsnap the two gang latches at the bottom front of the MFB and Alarm
Board, and swing downward.  Squeeze the boards together and slip off
the spring clip.
4. Carefully slide the DEFINITY LAN Gateway system from the switch
carrier.  Handle with care; the system weighs 6.2 pounds.
5. Disconnect the Interboard bus cable from the top edge of both boards
using the pull tab.
6. Remove the three socket-headed slotted screws that hold the MFB to the
alarm board.
7. Separate the two boards. If the alarm Board is to be replaced, remove the
disk and tape drives from it as described in Replacing the Disk/Tape
Drive in this chapter.
Replace the MFB or Alarm Board using the above steps in reverse order.  Note
the play between the boards when they are together.  This allows the system to
be easily seated into the switch carrier.
Cleaning the Tape Headbbbbbbbbbbbbbbb
The tape drive requires manual cleaning of its tape heads every three months or
after every 100 passes. Use the provided kit that includes a cleaning tape
cartridge, cleaning sticks, and cleaning solution, and follow these steps.
1. NEED PROCEDURE
2.
!CAUTION:
Ð The cleaning solution is highly volatile. Keep it away from high
temperatures and direct sunlight.
Ð Use the specified cleaning solution only. The head may be damaged
if other types of solutions are used.
Ð People with sensitive skin should use rubber gloves for protection.
Ð Do not use broken cleaning sticks with partially detached pads.
Ð Discared cleaning sticks after four to six uses.  If the device becomes
extremely dirty, replace the cleaning stick after one use.
Replacing the Tape Cartridgebbbbbbbbbbbbbbb
The DEFINITY LAN Gateway system maintains a count of write passes on a
working tape cartridge. When this count reaches 150, a warning alarm is raised
(FROM DEF AUDIX - WHAT TO SUBSTITUTE?) At this point, the cartridge
should be replaced. The system administrator must do this job.
1. NEED PROCEDURE
4-14  Issue 1  January 1996 
						

							Maintenancebbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
!CAUTION:
Check that backup tapes are not write-protected; the tab is positioned
closest to the end of the cartridge (it will cover the deeper inset). On the
generic tape, ensure that the tab remains in the write-protected position.
Replacing the Disk/Tape Drivebbbbbbbbbbbbbbb
To remove either the disk drive or the tape drive from the Alarm Board, refer
back to Figure 4-1 and follow the steps below.
!WARNING:
Static electricity can be destructive to system parts.  Use an anti-static wrist
strap whenever removing or installing a DEFINITY AUDIX system. Also use
an anti-static mat when taking the system apart to replace circuit packs or
storage devices.
1. Ensure that the users know you will be powering down the system and
disrupting service.
2. If it is not already shut down, bring the system to the MSHUT state.
(From the Main Menu, select Maintenance, Reset System, and then
Shutdown.)
3. Carefully slide the system from the switch carrier. Handle with care; the
system weighs 6.2 pounds.
4. Cut loose and remove the tie wrap that holds the power cable and the
tape drive SCSI bus cable against the Alarm Board.
5. Disconnect the SCSI bus cable from the Alarm Board that is connected to
the drive being replaced, using the pull tabs. (This sentence is unclear;
please clarify.)
6. As shown in Figure 4-6, unlock each of two retaining pins (B) from the
slots along the edge of the Alarm Board that hold the drive in place. Slide
out both pins (C); this releases the drive from the board.

7. Disconnect the power and SCI bus cables from the drive.
8. On the tape drive, pry off the stainless steel EMI shield. Note that the
narrow end of the cover fits over the ridge above the option jumpers; the
wide end locks over the mounting bracket.
