Site Inspections
For the purposes of a Release 8r upgrade, most Release 5/6si systems are
already equipped with the correct lightwave transceivers. Any older versions of
these components must be replaced. The earlier versions of lightwave
transceivers included the 4-series transceivers (4A through 4F). These
transceivers supported fiber connections up to 7,000 feet (2133 m). Order the
correct transceivers according to a separate PEC.

Power and Ground
The new multicarrier PPN cabinet or any EPN cabinet added for the upgrade can
be either AC or DC powered. If an added cabinet is powered differently from the
existing cabinets, the existing cabinets do not have to be converted since mixed
power configurations are allowed. However, the system’s power and ground
must be modified so the AC powered cabinets are grounded to the same
single-point ground bar as the DC powered cabinets.

DC Isolator
Each management terminal connected to a DC-powered cabinet, by the
asynchronous EIA RS-232 interface, requires a 116A isolator. The isolator is
inserted at the RS-232 interface between the terminal and the interface
connector to isolate ground between the system and external adjuncts.

Emergency Transfer Stations
During routine operation, the ground for the emergency transfer stations is
derived from the system’s auxiliary cable. Disconnect this ground during the
upgrade to disable the stations. A ground strap is run to the emergency transfer
panel. Connect this strap shortly after removing power and disconnect it just
before restoring power to the upgraded system.

Converting the Translations
The translations in the Release 5/6si system must be copied to a spare
translation card and sent to Software Technical Support (STS) to be converted
and written to a Release 8r removable media. This process takes 2 weeks. The
Release 8r media (including 1 with translations) must be on-site before the
upgrade begins. For each Release 8r processor, 2 media (1 system disk and 1
backup removable media) must always be retained on site with the system.
