Upgrading option 51C to option 61C

Equipment required

To upgrade an option 51C system to an option 61C system, you must upgrade
both the hardware and the software. Upgrading the hardware consists of:
— installing a Core/Network module next to the existing option 51C
column
— installing an IPE module on top of the existing option 51C column
— installing new cables
Upgrading the software consists of:
— installing new system software
— 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 X11 release 21 compatibility
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.
Refer to Product compatibility (553-3001-156) for equipment compatibility
