Dumping Memory to a	To write a memory dump to a TFTP host, you must set the boot protocol
TFTP Host	to TFTP, and the TFTP Upload Path parameter in the firmware
	configuration must indicate where the dump should be written onto the
	host. Refer to your TFTP server documentation to determine the
	appropriate directory. For information about the TFTP Upload Path
	parameter, refer to Table 4-3 on page 4-11.
Dumping Memory to	You can dump memory to the communications server’s diskette drive
Diskettes	only if the Auto-Reboot option has been disabled before the crash, and if
	the reset switch on the server’s front panel has not been pressed. Use the
	Firmware Configuration Utility to set the Auto-Reboot parameter to
	“Boot monitor,” as described in Chapter 4, “Configuration.” If this
	parameter is set to “Reboot only,” the communications server reboots
	automatically after a failure, overwriting RAM. If it is set to “Upload
	then reboot” the communications server does not allow a memory dump
	to be written to a diskette.
	To write a memory dump to the CS/2600 diskette, you need four or
	more high-density (2 MB) 3.5-inch diskettes (1.44 MB formatted). You
	do not need to format the diskettes. The du command automatically
	performs this step.
	The memory dump procedure reinitializes the monitor and saves the
	contents of memory. To write the memory contents to diskette, follow
	these steps:
	1 Enter monitor mode, as explained in “Entering the Firmware Monitor”
	on page 4-1.
	In some instances, a crash may leave the disk drive unusable because
	some monitor parameters were overwritten. In this case, the server may
	respond with an error message. To recover, enter the soft reset
	command:
	k
	2 From the console, enter the dump command:
	du
	The server prompts you with the following:
