To upgrade an option 51 to a Meridian 1 option 61C, you must upgrade both
the hardware and the software. Upgrading the hardware consists of the
following:
— installing a Meridian 1 option 61C next to the option 51
— removing network equipment from the option 51
— connecting the option 51 to the option 61C
Upgrading the software consists of the following:
— for those customers who so choose, sending the customer database disks
to Northern Telecom for conversion
— for those customers who choose to convert the database on-site,
converting the customer database to a higher release on the option 51 and
converting it to X11 release 21 on the option 61C
Tables 9-7 and 9-8 list the minimum items required to upgrade an
AC-powered or DC-powered system to an option 61C. Some configurations
may require items not included in the tables. All required items must be
identified and on hand before you begin the upgrade. Whenever a new
column is installed, you must also provide NT8D49AA Column Spacer Kits
and P0699724 Modular Side Covers.
Letters at the end of the part number may represent the minimum vintage of
the upgrade equipment. Only equipment of that vintage or later can be used.
