1.3.8 LANVIEW Diagnostic LEDs
LANVIEW diagnostic LEDs serve as an important troubleshooting aid by
providing an easy way to observe the status of individual ports and overall
network operations.
Chapter 4 provides details about the 6H123-50 and
6H133-37 LANVIEW LEDs.
1.3.9 Year 2000 Compliant
These products have an internal clock that can maintain the current time
and date beyond the year 1999.
1.3.10 Runtime IP Address Discovery
This feature enables the 6H123-50 and 6H133-37 to automatically accept
an IP address from a Boot Strap Protocol (BootP) or Reverse Address
Resolution Protocol (RARP) server on the network into NVRAM without
requiring a user to enter an IP address through Local Management.
When the 6H123-50 and the 6H133-37 are connected to the network and
powered up, Runtime IP Address Discovery (RAD) checks the 6H123-50
and the 6H133-37 for an IP address. If one has not yet been assigned
(6H123-50 and 6H133-37 IP address set to 0.0.0.0), RAD checks to see if
any of the interfaces have a link. If so, 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 out at an interval of 1 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 BootP server, or
an IP address is entered using Local Management.
