Upgrading LE, A, M, MS to Option 21

Upgrading method

Equipment required

This chapter describes how to upgrade an existing SL-1 LE, A, M and
Meridian SL-1 MS to a Meridian 1 Option 21.
The upgrading method consists of replacing the entire Common Equipment
(CE) with new common equipment used in the Meridian 1 Option 21
system.
Essentially only the existing peripheral and power equipment remains in
place in this upgrade.
It is important that all steps are carried out in order and that none are left
out. All preliminary steps must be done prior to the specific procedure for
each shelf upgrade.
Table 2-1 lists the items that are required to upgrade an SL-1 LE, A, M and
Meridian SL-1 MS system.
