7 Confirm the Meridian 1 Machine ID (system ID).
¥ Type LD22 at the Meridian 1 console, and press [Return].
¥ At the REQ prompt, type TID and press [Return]. Information
similar to the following is displayed:
TAPE ID:
LOADED xxxx
DISK/TAPE xxxx
Your Meridian 1 machine ID, a string of up to eight characters,
appears in place of the ÒxxxxÓ.
¥ Log in as maint on the Application Module, and use the showid
command (as described in Chapter 2, ÒApplication Module
commandsÓ).
If the Meridian 1 machine (system ID) does not match the machine ID
given in response to the showid command, the AML cannot function.
Contact your Nortel support personnel for the correct Application
Module software.
8 Check ESDI or MSDL port configuration on the Meridian 1.
There are several parameters that must be configured correctly in
LD17. Print from LD22 and compare the parameter values with the
information below. (An Option 11 IPE Module does not support an
MSDL card.)
¥ The link is full duplex and synchronous. It uses internal clocking
and is a direct connection to the Application Module.
¥ The speed of the link is 19200 bps.
¥ If the DTE/DCE configuration is not set up correctly, the AML
will not establish. By default, the ESDI or MSDL port is
configured as DCE because the Application Module side is
configured as DTE.
¥ IADR must have a value of 3 and RADR must have a value of 1.
¥ The user type is CMS (Command and Status Link).
¥ The Value Added Server ID (VAS ID) is a number between 0-15,
and must be unique for each ESDI defined.
