Page 43: Chapter 3 Rom Monitor Commands
GENERAL This chapter describes the ROM Monitor commands. These commands are accessed through a terminal connected to port 1 when the CSMIM-T1 is in SETUP mode. Pressing the SETUP switch within 3 seconds of powering up puts the CSMIM-T1 into Set Up mode.
Page 44 Table 3-1 Displays and sets EEPROM values relevant to network addr [-d] addressing, including the CSMIM-T1’s Internet address. Manually boots and loads the CSMIM-T1’s operating boot [-v] [<ﬁle>] code. Erases the existing Flash memory and copies a new boot [-l] [<ﬁle>] image to Flash.
Page 45: Commands
Internet address. Enter Internet addresses using the standard decimal dot (.) notation. The addr –d command displays the CSMIM-T1’s Ethernet address, IP address, subnet mask, broadcast address, preferred load host address, preferred dump host address, load/dump gateway address, IP encapsulation type, and Load Broadcast.
Page 46 Type of IP packet encapsulation: <ethernet> Load Broadcast: Y The CSMIM-T1 must have an Internet (IP) address in its memory before it can load its operational image across the Ethernet via the IP protocol. Therefore, you must enter the IP address before booting the CSMIM-T1 from a UNIX load host.
Page 47: Boot
CSMIM-T1 uses the generic mask for the specified IP address. The Remote Annex tries to boot from a preferred UNIX load host. If you do not define a preferred load host, the CSMIM-T1 broadcasts its load request on the subnet and loads software from the first host that responds.
