Upgrading R5si/R6si to an Avaya DEFINITY Server R
EPN running Avaya MultiVantage Software
Usable Circuit Packs
Every circuit pack must conform to the minimum usable vintage requirements.
Those circuit packs shipped in the new PPN or shipped loose with the new EPN
equipment must meet the usable vintage specifications. In addition, at a presale
site inspection, the remediation process must check the vintages of every
Release 5/6si circuit pack that will be reused and replace those circuit packs with
unusable vintages. Refer to Technical Quarterly, Reference Guide for Circuit Pack
Vintages and Change Notices, for current information about usable vintages.
Site Inspections
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 7000 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.
