Appendix
9H423-26 Module Specific
Information
Introduction
This appendix contains local management information that is specific to the
9H423-26 Fast Ethernet Switch Module.
The 9H423-26 Switch Module has 26 ports:
• 24 ports (two fixed RJ21 connectors)
• 2 ports (two fixed MMF SC connectors)
This module can operate in either full duplex or half duplex mode.
Auto-negotiation provides support for 10 Mbps and 100 Mbps speeds at both half
and full duplex. 100Base-FX supports 100 Mbps speed at both half and full
duplex.
Auto-negotiation allows the module to automatically use the fastest rate
supported by the device at the other end (either 10 Mbps or 100 Mbps at either
half or full duplex). This technology is similar to how modems negotiate
transmission speed to find the highest transmission rate. Similarly,
auto-negotiation determines the highest common speed between two devices and
communicates at that speed. If no common speed is detected, the device will be
partitioned.
Modifying Fields and User Privileges
To modify fields on this module, you must have read-write or super-user
privileges. If you have read-only privileges, you can view information; however,
you cannot modify any fields. For more information about user privileges and
community names, see the
SmartSwitch 9000 Module Local Management User’s
