Booting From Flash Ram; Booting From The Network; Using Console Commands To Boot - Digital Networks DECserver ConX4 Installation And User Manual

Loading the DECserver Network Access Software
Before you load the software, optionally attach a terminal to the console port. The DECserver displays status
messages on the console terminal while the boot sequence is running. Status messages indicate the Ethernet
address of the DECserver, the name of the load image it is looking for, and the current stage of the boot
process.

Booting From Flash RAM

Once the self-tests are complete, the DECserver begins the boot sequence to load the software from Flash
RAM. Port Activity LED 4 goes on to indicate a Flash RAM boot sequence is in progress. A typical Flash
RAM load takes about 10 seconds.
If you want to abort a boot from Flash RAM, it is only during these 10 seconds when the software is loading
that you can abort the Flash RAM load by pressing the Reset-to-Factory button until Port Activity LED 4
blinks.

Booting From the Network

If the correct image is not found in Flash RAM, the DECserver proceeds to perform a network load. When
you start the boot process, the Network OK LED blinks continuously and the system OK LED remains on
indicating that the DECserver is attempting to load the software from the network.
During the network boot sequence, the DECserver searches for a load host. The DECserver tries both MOP
and BOOTP/TFTP protocols in a factory-defined order. The boot sequence includes a wait period after
passing through all the boot protocols. Once the DECserver finds a load host, it records the protocol and load
host in its permanent database. The software is then downline loaded from the load host.
Port Activity LEDs 6, 7, or 8 go on to indicate which protocol the DECserver is using to downline load the
software. Port Activity LED 5 goes on to indicate that all attempts to find a load host have failed and that the
DECserver will remain in a wait state for a designated period of time before trying again. Port Activity LED
4 goes on to indicate the software is being booted from Flash RAM (refer to Table 2–3).

DECserver Network Access Software Installation documentation.

Using Console Commands to Boot

If you program Flash RAM with a nonstandard boot image name and a load host is not available, pressing the
reset-to-factory button may leave the DECserver unbootable. A nonstandard boot image name is any name
other than MNENG4.
