2.2.4Ring Speed

The operating ring speed for the STHI may be set via the Ring Speed Switch on the front face of the STHI or by MIB commands via the SNMP Tool screen in Local Management.

The STHI hub’s Ring Speed switch setting is read only at power-up. In order to change the ring speed via the Ring Speed switch, the user must first change the switch setting and then reset the STHI (see Section 4.3, The Reset Button).

MIB commands override the Ring Speed switch setting. Once the switch setting has been overridden, the MIB command ring speed setting will remain in effect at all subsequent power-ups as long as the switch setting is not changed. MIB commands are accessible through the MIB Navigator screen on the intelligent hub’s Local Management application and through other SNMP network management software packages including Cabletron Systems’ Remote LANVIEW®/Windows.

The user may cancel the MIB override and regain switch control over the STHI hub’s ring speed by changing the current switch position and resetting the STH by the reset button.
