The Reset Button - Cabletron Systems STHI User Manual

Management Failure
If the MGMT LED is red, try resetting the STHI. If this does not resolve the
problem, contact Cabletron Systems Tech Support. Meanwhile, the STHI
will continue to operate, but will not provide Beacon Recovery or
statistical monitoring.

4.3 The Reset Button

The STHI incorporates a recessed Reset button (see Figure 4-1). Pressing
this button causes the STHI to clear all counters, run all startup
diagnostics, and reload the flash resident firmware into the CPU local
memory. It does NOT initialize Non-Volatile Random Access Memory
(NVRAM), the battery-backed random access memory where the STHI
stores network management parameters. (See also Section 4.4, NVRAM
Reset Switch.)
