Confirming a Hardware/Firmware Failure
Defective hardware or firmware can cause the adapter to indicate a
self-test failure as follows:
H No indicators light during power on
H The indicators light and remain amber
H The LAN-Link, LAN, and GPIB indicators blink red after the
self-test at power on.
To confirm a hardware or firmware failure, do these steps:
1. Supply power to the AD007 adapter.
2. If no indicators light, check power connections at the following
components:
a. line source to power cord
b. power cord to power supply
c. power supply to the DC input jack on the back of the
AD007 adapter
3. If indicators light, wait 30 seconds for the self-test to complete.
Blinking indicators at the beginning of power on indicate that the
hardware self-test is in progress.
4. To indicate a successful self test, the LAN-Link, LAN, and GPIB
indicators simultaneously blink green before automatically
starting the LAN discovery (DHCP/BOOTP request) loop. See
Table 2.
5. To indicate a hardware failure in the adapter, the adapter will
indicate one or more of the following
a. The LAN-Link, LAN, and GPIB indicators simultaneously
blink red after the 30-second self test is complete.
b. All indicators light and remain amber.
c. The LAN-Link, LAN, and GPIB indicators do not
simultaneously blink green before beginning the LAN
discovery.
