These methods are described in the following sections.
Once you access the monitor utility, you are in monitor mode, indicated by
the angle bracket prompt (>).
To access the monitor utility by powering on the server without a boot
source, follow these steps:
1 Make sure that there is no diskette in the disk drive (Model CS/3100 only)
and that the server cannot use a network boot source (an RBCS or TFTP/FTP
server).
If a diskette is in the disk drive, remove it. If the communications server is
configured to use a network boot source, disconnect it from the network, or
make sure that it is not listed in the boot database of an RBCS or TFTP/FTP
server. To determine whether the server is in the boot database of an RBCS
server, refer to the Remote Boot and Configuration Services User's Guide.
2 Turn the unit power or, if it is already on, press the reset switch on the front
panel to reboot.
The server tries to boot. (The booting process takes a few minutes.) Because
the boot source is not present, it displays the following message:
Do you want to enter monitor (Y/N)?

at the prompt.
