Upgrading Cpu 0 - Nortel Meridian 1 Manual

Upgrading CPU 0

Note 1: Make sure a terminal is connected to J25 on the I/O panel in
Core 0. If you are using only one terminal, connect it to Core 0; if you
are using a switch box for the CPSI ports, set the switch to Core 0. Verify
that the terminal is set for 9600 baud, 7 data bits, 1 stop bit, space parity,
full duplex, XON protocol.
Note 2: If you upgraded the CP and IOP ROMs on Core 1, do the same
for Core 0. Insert diskette 1 from the software upgrade package into
IOP/CMDU 0. Press the MAN RST button on the CP card in Core 0. At
the main menu, select option <e> for the CP ROM, follow the on-screen
directions, and then select option <f> for the IOP ROM. Refer to
"Software Installation Tool reference," Software conversion procedures
(553-2001-320). Do not install software or the customer database on
Core 0.
