Troubleshooting
The AsantéHub 1012 does not require any routine maintenance. There are no user
serviceable parts in the AsantéHub.
If you cannot identify and correct a fault using the testing procedures described
below, contact Technical Support. See “Technical Support” in this manual.
This chapter describes troubleshooting based on the hardware display. AsantéView
also provides network diagnostic routines, graphical LED and link status displays, and
real-time statistics on network performance. For information on these features, refer
to the AsantéView Users' Guide.
Interpreting the LEDs
Hardware aids to testing and monitoring your network’s status include the LEDs on
the AsantéHub, on the network interface card, and on the TP-MAU. In general, the
LEDs give information about the status of a particular unit or function. This section
covers how to read the LEDs on the AsantéHub 1012.
Start-up Display
When you first turn on the AsantéHub, all the LEDs switch ON in sequence, while the
hub goes through a series of internal diagnostics. The start-up (diagnostic)
sequence and hardware failure indication were described in Chapter 1, “Quick Start.”
Normal Operational Display
After the diagnostics have been passed, LEDs resume normal operational status.
The table on the following page gives a brief description of each LED as it appears
during normal operation. (Normal operation may include packet collisions or errors.)
Note: For detailed information on LEDs, see Table 2-1, “LED Status Indications.”
