If a high temperature condition existed but no longer does, this message
appears:
Hardware: (HIGH TEMP SEEN)
To remove this message, enter the clear alarm command, as shown below:
clear alarm [Enter]
This is the only environmental condition that requires you to invoke the clear
alarm command. The other two danger conditions are cleared only when the
condition no longer exists. Otherwise, the warnings reappear with every
subsequent command and new line that you type.
Reset Function
The reset function reinitializes the hub and runs the power-on self-tests (POST).
You should perform a reset before removing or adding a module to the hub. Any
devices connected to the hub when a reset is performed are momentarily
disconnected until the tests are completed. The hub then attempts to reconnect
the devices.
Before the reset begins, you are prompted to confirm the reset request. This
gives you the opportunity to make changes in network connections, such as
entering the disconnect command, which disconnects the hub from the ring.
This allows you to avoid other problems that could occur with an unexpected
interruption of service.
You can perform the reset function in one of two ways:
Enter the reset command on the command line.
Press the RESET button on the management module.
The RESET button on the management module is recessed behind the faceplate.
To access the RESET button, insert a small pointed object, such as the tip of a
sharp pencil or end of a bent paper clip, into the hole below the RESET label.
Pressing the RESET button performs the two functions described below:
