4.2.3. Software Upgrades
Software upgrades are similar to the initial installation procedure discussed above. Each time the BCU/CAL boots, it
will check to determine whether a floppy diskette is installed. If a diskette is present, it will be scanned to check whether any
BCU/CAL installation files are present. If applicable files are detected, they will be copied to the appropriate system disk
directory. As in the initial installation procedure, the operator will be prompted to remove the current diskette and insert the
next one.
This method also applies to customer modifications to the contents of Installation Diskette 4. Specifically, if (new)
changes are made to either the IP.DAT or CAL.DAT files, the BCU/CAL should be rebooted with the modified diskette
inserted in the floppy drive.
Note that previous software loads and user configuration files are not destroyed when an upgrade or configuration change
is installed. The BCU/CAL archives up to 3 of the last installations in the "1.2/backup" directory. These can be retrieved by
the operator in the event of problems with a new software installation, or errors in the end user modified configuration files.
4.3. CAL TERMINAL SERVER CONFIGURATION
The CAL feature of the BCU/CAL supports up to 2 Emulex P2516 Terminal servers. Each terminal server provides 16
serial ports. Of these, 15 are readily accessible for System Manager site controller interfaces, with one port (port 1) being
used for initial terminal server configuration.
Temporarily disconnect the Ethernet LAN connection from the terminal server. Connect a “dumb” VT100 compatible
terminal to port 1 of the terminal server to be configured. This corresponds to port 1 on the BCU/CAL distribution panel for
the first terminal server and port 17 for the second terminal server. The terminal should be configured for 9600 baud, 1 start
bit, 1 stop bit, and no parity.
Log in to the first terminal server under the privileged account.
If you are greeted with a
#
prompt, first execute the following command:
# access
If the server requests a password enter
<CTRL-Z>.
Server> su
Password> system
system is the default privileged account password. This can be changed later.
Set the terminal type used to configure the server.
Server>> change port 1 type VT100
Define the IP address and subnet mask of the terminal server. The IP address, terminal_server_ip, must reflect the
associated address defined in the CAL.DAT file. The subnet mask, subnet_mask, should be the same as defined for the
BCU/CAL in the IP.DAT configuration file.
Server>> set server ip

Server>> set server subnet mask
