The Reset Button

Management Failure 4

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.)
