Status
summary
1 byte
Module status summary. This field is a summary of the
OpenVMS and firmware status fields. The field should be
updated whenever OpenVMS or firmware status fields are
updated. Codes are initially copied from the module ID
EEPROM. Valid codes (in hex) are:
A5 = Module is good.
B4 = Module is bad, marked by OpenVMS. See
OpenVMS status field.
C3 = Module is bad, marked by firmware. See firmware
status field.
FF = Module is bad, marked by OpenVMS and
firmware.
OpenVMS
status
1 byte
Module status as marked by OpenVMS (and maintained by
OpenVMS). Codes are initially copied from the module ID
EEPROM. Valid codes (in hex) are:
A5 = module is good.
non A5 = module is bad.
Firmware
status
1 byte
Module status as marked by firmware (and maintained by
firmware). Codes are initially copied from the module ID
EEPROM. Valid codes (in hex) are:
A5 = Module is good.
non A5 = Module is bad.
Module name
4 bytes
ASCII module name. Copied from the module ID EEPROM.
Module serial
number
12 bytes
Module serial in ASCII. Copied from the module ID
EEPROM.
Hardware
revision
6 bytes
Identifies the module hardware revision. Copied from the
module ID EEPROM. Divided in:
Minor revision (bytes 02:00)
Major revision (bytes 05:03)
Firmware
revision
2 bytes
Console/diagnostic firmware revision of the module. Copied
from the module ID EEPROM. Divided in:
Minor revision (byte 00)
Major revision (byte 01)
Software
revision
2 bytes
Functional firmware revision of the module. Copied from
the module ID EEPROM. Divided in:
Minor revision (byte 00)
Major revision (byte 01)
