Connectivity

1.1CONNECTIVITY

The 6H352-25 connects to Ethernet networks or workstations through the front panel connectors. The ports support Unshielded Twisted Pair (UTP) cables with an impedance between 85 and 111 ohms at lengths up to 100 meters. The ports are IEEE 802.3 10BASE-T and 100BASE-TX compliant.

1.2OPTIONAL HSIMs AND VHSIMs

Optional HSIMs and VHSIMs are available from Enterasys Networks for additional connectivity to various networking technologies. The HSIMs and VHSIMs available for the 6H352-25 are listed in the Release Notes shipped with the module.

1.3RUNTIME IP ADDRESS DISCOVERY

This feature enables the 6H352-25 to automatically accept an IP address from a Boot Strap Protocol (BootP) server on the network without requiring a user to enter an IP address through Local Management.

When the 6H352-25 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 IP address set to 0.0.0.0), RAD checks to see if any of the module interfaces have a link. If a link is discovered, RAD sends out Reverse Address Resolution Protocol (RARP) and BootP requests to obtain an IP address from a 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 6H352-25 will reboot after RAD is successful.
