Exit
Option 23, Exit, allows you to exit the console. When you choose this option, the
console session is terminated and the following appears:
Console session terminated ...
If you are connected to the session by a modem, then the phone line is also
disconnected. After you exit, you must wait a minimum of 5 seconds before you
try to re-establish a connection. Press the Return key to reconnect to the console.
You must then supply the correct password to gain access to the console.
Upgrading the DECagent 90
The DECagent 90 can be upgraded in the field (on site). Operational code is
stored in flash RAM and is downline loaded using the MOP protocol. A downline
load host triggers the DECagent 90 to request a downline load of a specified
software image. The image is initially loaded into a "landing pad" area of
RAM. After the transfer is complete and the software checksum is verified, the
DECagent 90 transfers the new image into flash RAM. The DECagent 90 then
resets and cycles through power-up.
The upgrade procedure is non-destructive. Programmable information pertaining
to the DECagent 90 and its clients is preserved.
Loading from a VAX Host
This section describes how to downline load the flash image through an Ethernet
network from a VAX host.
VAX Host Node Setup
Check to see if the VAX host is set up to allow downline loads. Circuit service
must be enabled.
To set up the VAX host for downline loading, use the following procedure:
1. Enter ncp by entering the following:
$ mcr ncp
Return
2. At the ncp prompt, enter the following:
ncp> sho circ qna-0 char
Return
Note
Use the appropriate Ethernet circuit. For example, sva, bna, qna, and so
on.
