Bridge Diagnostics

The AsantéBridge 1012 is equipped with on-board diagnostics that run when the bridge is powered on (cold start) or when reset, either from the front panel or with the Reset system command from the local management Conﬁguration Menu.

The diagnostics take a few seconds and are designed to check the overall health of the bridge and hub hardware and internal soft- ware.As the diagnostics run, the VT100 window will scroll, listing the separate tests and the results. Figure 3-1 shows a sample screen.

If one of the diagnostics should fail or detect a system malfunc- tion, an error message will be displayed in the window.Write down what it says and call Asanté Technical Support for help.

Figure 3-1 AsantéBridge 1012 Diagnostics

After the diagnostics are completed, the window scrolls up and shows the normal AsantéBridge 1012 local management menu.
