Overview

1.1.1Connectivity

The SmartSwitch modules connects to Fast Ethernet networks or workstations through the MT-RJ fiber optic ports on the front panel for 100 Mbps with duplex capability. These ports are in full compliance with the optical performance requirements of 100BASE-FX version of IEEE 802.3u. The 6H258-17 ports support multimode fiber optic cables up to 2 km. The 6H259-17 ports support single mode fiber optic cables up to 15 km.

SmartSwitches have a slot for an optional HSIM or VHSIM to provide additional connectivity to various networking technologies.

1.1.2Runtime IP Address Discovery

This feature enables the module to automatically accept an IP address from a Boot Strap Protocol (BootP) server on the network into NVRAM without requiring a user to enter an IP address through Local Management.

When the module is connected to the network and powered up, Runtime IP Address Discovery (RAD) checks the module for an IP address. If one has not yet been assigned (module and 6C105 chassis IP address set to 0.0.0.0), RAD checks to see if any of the module interfaces have a link. If so, RAD sends out Reverse Address Resolution Protocol (RARP) and BootP requests to obtain an IP address from a RARP or BootP server on the network.

The RAD requests start at an interval of one per second. The interval then doubles after every transmission until an interval of 300 seconds is reached. At this point, the interval remains at 300 seconds. The RAD requests continue until an IP address is received from a RARP or BootP server, or an IP address is entered using Local Management.

NOTE

The module will reboot after RAD is successful.

1.1.3Full Duplex Switched Ethernet

Each switched Fast Ethernet port on the SmartSwitch supports 100 Mbps operation and can be configured to operate in Full Duplex Switched Ethernet (FDSE) mode. FDSE allows each port to provide up to 200 Mbps of bandwidth.
