Ipsi Placement Decisions; Installing And Configuring The S8700 Or S8710 Media Server Complex - Avaya S8700 Series Manual

IPSI placement decisions

In a direct connect system we install IPSI(s) in the PPN rather than an EPN because of the fiber
connections and administration among the PNs. If the IPSIs are installed in an EPN in a
3-cabinet system, you would have to reconnect and readminister the optical fiber connecting the
EI circuit packs. In a 2-cabinet system, this would not be a problem. Even in a center stage
switch (CSS) system, installing IPSIs in the PPN is a good idea because it speeds up the
system startup.
You want to put the rest of the IPSIs in as many different cabinets as you can. For example,
putting IPSIs in both halves of a dual PN cabinet is not a good idea; if the cabinet dies, you lose
2 IPSI PNs. However, if in a 10-EPN system, 7 of the EPNs are DS1-C remoted and the other 3
PNs are 1 PPN cabinet and 1 dual PN cabinet, then putting IPSIs in both halves of the dual PN
and the converted PPN eliminates running remote IPSI connections.
Installing the IPSIs in the PNs, including the PPN, ahead of time saves downtime because you
can install, connect, and program the IPSIs and test their connectivity to the media server
ahead of time. You also can upgrade the firmware on the IPSIs that need it before the actual
cutover. Depending on how many IPSIs are installed, this could save a considerable amount of
downtime. Installing IPSIs in the PPN and then re-installing them in the new carriers may seem
a waste of time, but, again, it allows you to make sure they are working correctly before the
cutover.
Installing and configuring the S8700 or S8710 Media Server
complex
This stage consists of the physical rack installation of the S8700 or S8710 Media Servers,
uninterruptible power supplies (UPSs), Ethernet switches, and connecting cables. After
completing the physical installation, the components are configured, the license and Avaya
authentication files are installed, and the software is upgraded and patched.

This stage can be done any time before transferring the existing translations. This stage is not
service affecting to the existing DEFINITY ECS system.
