Problem Action
Power
• Ensure that the device is plugged into an active outlet.
• Ensure that the power switch is on.
• If the device has a fuse, replace it.
• If the device has a circuit breaker, reset it.
Cables
• Ensure that the device cable is secure at both ends.
• If the cable is spliced, ensure that all junctions are secure.
• Verify all device cable connections at couplers, adapters, and
cable concentrators (harmonica).
• Inspect the cable for cuts and crimps. If necessary, use another
cable.
• Ensure that the maximum allowable cable length is not exceeded.
Refer to the access server hardware documentation.
Speed Match the access server port speed to that of the device. If Autobaud is
enabled, the port and device speed match automatically. If split-speed is set,
Autobaud must be disabled.
Parity and
character size
Match the access server port parity and the character size to that of the
device. The access server supports devices with odd, even, mark, space, and
no parity. It supports character sizes of 7 and 8 bits. If Autobaud is enabled,
parity and character size for the port and device match automatically.
