5.4.2 Tabletop
Two alarm relay contacts “Urgent” and “Non-urgent” are located on the Monitor connector of the ta-
bletop.
Alarm Conditions
Urgent Alarm:
! At least one of the tabletop - LEDs is red
Non-urgent Alarm:
! At least one of the tabletop - LEDs is amber and none of the tabletop - LEDs is red
Note: ! In case of remote powering the alarm relays are kept inactive to save power
! If alarm cut off is activated (ACO = on), the alarm relays are disabled.
5.5 Initialization Errors
At system startup, various hardware selftests are performed. If any initialization errors occur, the
startup procedure will be aborted and the Monitor of the Watson 5 Ethernet plugin displays an error
message.
On the Watson 5 Ethernet tabletop an initialization error code in hexadecimal representation is dis-
played:
Error Code Error Variable Initialization Error
0x0001 RAM_ERROR Microcontroller RAM test failure
0x0002 EEPROM_ERROR EEPROM test failure
0x0004 XDSL_ERROR Framer initialization failure
0x0008 TCVR_A_ERROR DSL transceiver failure (Loop A)
0x0010 TCVR_B_ERROR DSL transceiver failure (Loop B)
0x1000 TCVR_C_ERROR DSL transceiver failure (Loop C)
0x2000 TCVR_D_ERROR DSL transceiver failure (Loop D)
0x0080 ETHERNET_ERROR Ethernet interface initialization failure
0x8000 SW_PROTECT_ERROR Software Copyright Protection Error
Table 5-6: Software Initialization Errors (tabletop modem).
If several errors are detected simultaneously then the error code displayed is a combination (OR) of
the individual error codes, e.g. 0x83 will be displayed if during selftest the RAM test fails, the
EEPROM test fails and the Ethernet interface cannot be initialized.
