Auto-Initializing The Remote Annex - Bay Networks 5393 Hardware Installation Manual

Auto-initializing the Remote Annex

9 Verify that the Remote Annex is on-line by entering the net
command. The following prompt appears:
Enter Segment to be used [1]:
A "pass" or "fail" message is displayed. If fail is displayed, try
verifying the network from another device.
Once the Remote Annex is on-line, you can download the image
software to the server (see
Loading the Image on page 2-28).
The Remote Annex is distributed without an IP address or preferred
load host defined in ROM. When the device is booted, the Remote
Annex attempts to auto-initialize itself using BOOTP (bootstrap
protocol) and RARP (Reverse Address Resolution Protocol).
The Remote Annex supports the BOOTP and RARP protocols. Use
these protocols to obtain boot information from a UNIX host without
requiring any manual set-up on the Remote Annex.
BOOTP allows a diskless client to determine its IP address,
the IP address of the server, and the name of the file to be
loaded into memory.
RARP maps a hardware address into an IP address.
The ROMs invoke this system of acquiring boot information when a
boot is initiated and the Remote Annex is not initialized. Under this
condition, the Remote Annex first tries to get boot information via
BOOTP or RARP.
