Upgrading Hardware In Each Port Network; Replacing Tone Clocks With Ipsi Circuit Packs And Replace Maintenance Circuit Packs; Determining Ipsi Placement In Port Networks - Avaya S8500 Manual

Upgrading hardware in each port network

In IPSI-controlled PNs you must replace the existing tone-clock and maintenance circuit packs with a
TN2312BP IPSI circuit pack and TN775D or later maintenance circuit pack. You must also replace
TN776 (SI) and TN570 (R) Expansion Interface circuit packs with TN570B, vintage 7, or later circuit
packs.

Determining IPSI placement in port networks

Determine which PNs get the IPSI circuit packs. Not all PNs require them. Port networks that do not
house an IPSI have an Expansion Interface (EI) circuit pack that controls the PN. These EI-controlled
PNs are assigned automatically to an IPSI at system initialization. The balancing of EI-controlled PNs
amongst available IPSIs is also done automatically.
Also, with Release 2.0 or later of Communication Manager, you are allowed to put an IPSI in a DS1-C-
remoted port network.
The following are the rules and guidelines for placement of IPSI circuit packs.
Rules:
•
When placing an IPSI in a DS1-C-remoted port network, make sure that the non-remoted IPSI is
administered first and that the
not have to be set to no. However, if it is set to y, customers need to run Ethernet from the IPSI
and there is limited control (1:2 versus 1:5).
•
The reference IPSI (the one whose serial number is used in the license file) is placed in the PN
with the shortest Ethernet connection to the media servers. This minimizes the amount of data
network that could fail between the IPSI and the media servers causing the system to switch to No
License mode.

NOTE:
Before beginning, read this procedure and
on page 107 to familiarize yourself with them. If using DHCP server, setting the Switch
ID and Cabinet number on the IPSI circuit pack can be done at initial installation.
However, there are certain sequences that need to be completed prior to a predetermined
time-out interval. If the Switch ID and Cabinet number are not set when the circuit pack is
first plugged in it can be done later but it will require that the circuit pack be reseated. This
could result in an additional service interruption in a duplex reliability configurations.
