Status Number
Status Bits (continued)
Bit 6 The TRANS (Transceiver, such as Ethernet transceiver) bit indicates
whether the circuitry between the LAN IC and the LAN cable is
functioning. If this bit is not set, then the path between the LAN cable and
the LAN IC is operating properly. If this bit is set, then either the CPU
board or the I/O board must be replaced.
Bit 7 Timeout bit. If the Timeout bit is set, then bits 4, 5, or 6 will also be set.
Refer to the appropriate bit for a suggested course of action.
Bit 8 The Tx bit indicates whether the transmission portion of the MAC, ENDEC,
or TRANS test failed. Therefore, the Tx bit is used in conjunction with bits
4, 5, and 6. Refer to the appropriate bit for the suggested course of action.
Bit 9 The Rx bit indicates whether the receive portion of the MAC, ENDEC, or
TRANS test failed. The Rx bit is used in conjunction with bits 4, 5, and 6.
Refer to the appropriate bit for the suggested course of action.
Bit 10 The Parameters bit indicates the integrity of the LAN module self-test
parameters. If this bit is not set, then the parameters sent to the self-test
routine are correct. If this bit is set, then contact your nearest Agilent
Technologies Sales and Service Office.
Bit 11 The EPROM that is used to hold the Ethernet address, IP address, and
gateway address has been corrupted. If this bit is set, the LAN board
must be replaced.
