553-3001-250 Standard 14.00 August 1996
A module upgrade from an option 21 or 21E system to an option 51C consists
of upgrading both the hardware and the software. Upgrading the hardware
consists of the following:
— installing a Meridian 1 option 51C next to the option 21/21E
— removing the common equipment (CE) from the option 21/21E
— cabling the option 21/21E to the option 51C
Upgrading the software consists of the following:
— sending the customer database disks to Northern Telecom for conversion
or
converting the customer database to X11 release 21 compatibility for
those customers who choose to convert the database on-site
Alternatively, you can reenter the database on the option 51C after the
upgrade is complete.
Note: It is recommended that option 21/21E customers send the
customer database diskettes to Northern Telecom for conversion; contact
your Northern Telecom representative to arrange for this.
— defining the system configuration in the option 51C customer database
Tables 8-15 and 8-16 list the minimum items required to upgrade an
AC-powered or DC-powered system to an option 51C. Some configurations
may require items not included in the tables. All required items must be
identified and on hand before you begin the upgrade.
Letters at the end of the part number represent the minimum vintage of the
upgrade equipment. Only equipment of that vintage or later can be used.
Refer to Product compatibility (553-3001-156) for equipment compatibility
information.
