<COMB1>..<COMB4> is status on communication with Combiner Board 1 to 4.
<FOMASTER1:1>..<FOMASTER1:6> is status on communication with Fiber Optic
Modules 1 to 6 in rack 1.
<FOMASTER2:1>..<FOMASTER2:6> is status on communication with Fiber Optic
Modules 1 to 6 in rack 2.
<FOMASTER3:1>..<FOMASTER3:6> is status on communication with Fiber Optic
Modules 1 to 6 in rack 3.
<FOMASTER4:1>..<FOMASTER4:6> is status on communication with Fiber Optic
Modules 1 to 6 in rack 4.
Value can be:
0 means status is OK
1 means status is ERROR, or data not currently available (configurations error).
- (dash) means module is not installed.
Example:
GET COM
Reply:
01-- 00-- 00-- 000000 0000-- ------ ------
meaning that two racks are installed with 6 modules in first rack and two in second.
Communication between controller and Rack Communications Board 2 is failing, while
communications with all other modules are OK.
6.8 CRC – Status of EEPROM CRC
Displays status of the EEPROM CRC in active devices.
6.8.1 Usage
Attribute type: Read only
Each active device stores all settings and configurations in its own EEPROM memory so
that an immediate startup can be performed after power outage, and so that radio
coverage works as intended even if controller malfunctions.
On regular intervals the controller requests a checksum calculation of the EEPROM in
the radio devices.
If a failure is detected, the CRC error is flagged in the EEPROM of the active device so
that alarm status is known even after a power failure. This status is checked in EEPROM
of the Rack Communication Boards (RCB), Splitter Boards (SPLIT), Combiner Boards
(COMB) and the Fiber Optic Master Units (FOMASTER).
CRC alarms normally indicates a failing EEPROM and that module should be replaced.
This attribute replies with CRC status of the polled devices.
