2.7.2RARP

If the CSMIM-T1 does not receive a successful BOOTP response, it uses RARP to get the boot information. For a successful RARP retrieval, TCP/IP must be running on a host that is on the same network as the CSMIM-T1 and the host’s ARP table must be initialized with the CSMIM-T1’s Internet and Ethernet addresses (see the arp man page, arp -s).

The only boot information that RARP provides is the CSMIM-T1’s Internet address. The ROMs save this information in the inet_addr parameter. The ROMs use default information for the Subnet Mask and preferred load host. This means the ROMs will broadcast their request.

The host serving the CSMIM-T1 its boot information must be running on the same network because the CSMIM-T1 only broadcasts BOOTP and RARP queries.

If BOOTP and RARP fail, the CSMIM-T1 transmits an IPX advertisement Request for Service and a MOP Multicast boot request.

If all requests fail, the CSMIM-T1 returns to the ROM monitor (if in test mode) or continues the auto initializing procedure indefinitely (if in normal mode).

2.8SOFTWARE INSTALLATION PROCEDURES

Install the operational code on a UNIX host before loading it on a CSMIM-T1. Please note that although the CSMIM-T1 will run on a Novell system, it will not boot from Novell. The UNIX Installation Notes describe how to install software on a UNIX host, as well as a non-UNIX host. The CSMIM-T1 may also be booted from software loaded on another CSMIM-T1 containing Flash, or from its own Flash memory (see Section 2.7.2, Self Booting the CSMIM-T1).

When loading the CSMIM-T1 software for the first time, use the ROM Monitor commands.
