OPERATING PROCEDURES
STOP/RESET SWITCH
I-E96-202B
4 - 3
Solid Green
The MFP module is in execute mode.
Flashing Green
The MFP module is in execute mode but there is an NVRAM
checksum error, or the MFP module is in configure or error
mode.
Solid Red
The MFP module diagnostics have detected a hardware failure,
configuration problem, etc. and have stopped the module.
Additionally, LEDs one through eight will illuminate in a cer-
tain combination to display the error code.
STOP/RESET SWITCH
NOTES:
1.
Do not remove an operational MFP module under power unless
the stop/reset pushbutton has been depressed once, and the mod-
ule has halted (status LED is red and LEDs 1 through 6 are on). This
procedure must be followed when removing an MFP module from a
redundant configuration. An operational primary MFP module must
halt operation before control passes to the secondary MFP module.
2.
Firmware revision levels must be the same in the primary and
secondary MFP modules. If the firmware revision levels are different
and a failover occurs, the redundant MFP module may operate
erratically.
The stop/reset switch is a two-function switch. It stops the
module in an orderly manner thereby preventing glitches on
the bus. It also resets the MFP module. This switch is accessi-
ble through the opening on the faceplate. See Figure
for the
exact location of the opening. Since the opening is small,
pressing the switch requires a thin round object. Pressing the
switch once stops MFP module operation. Always stop an MFP
module before removing it from the module mounting unit.
Stopping the MFP module in this way causes the module to:
•
Save and lock the MFP module configuration.
•
Complete any nonvolatile memory write operations in
progress.
•
Deactivate all communication links.
•
Transfer control from the primary module to the secondary
module in redundant configurations.
•
Change the status LED color to red.
Once the MFP module is stopped, pressing the stop/reset
switch again resets the module. Reset the module to:
•
Reset the default values to the power-up values.
