Replacing Tone Clocks With Tn2312Bp Ipsi Circuit Packs In The Expansion Port Networks And Processor Port Network (Optional); Converting The Processor Port Network To A Port Network - Avaya S8500 Manual

This stage is service affecting for standard reliability configurations. As each PN is worked on, it is out of
service while the circuit packs are being changed. Service impact can be minimized for high or critical
reliability configurations by only working on the circuit packs in the standby carriers (MCC) or cabinets
(SCC).
Replacing tone clocks with TN2312BP IPSI
circuit packs in the
expansion port networks and processor port
network (optional)
Some PNs receive IPSI circuit packs. The TN2312BP Internet Protocol Server Interface (IPSI-2) circuit
pack takes the place of the existing TN2182 Tone Clock circuit pack and terminates control
communication with the S8700 or S8710 Media Servers. In existing PNs that receive IPSIs, flat ribbon
cables run between the IPSIs and the maintenance circuit pack to provide connectivity that is not
available via the backplane of older carriers. Once the IPSI circuit packs are installed, you must either
program the faceplate so a DHCP server can assign IP addresses to them or program static IP addresses
into the IPSI itself, depending on whether the control network is dedicated (private) or nondedicated
(through the customer's network).
You can accomplish this stage at any time before the actual cutover. The tone clock and IPSI circuit packs
are hot-swappable and can be changed out in the existing DEFINITY system. The IPSI circuit pack
provides the same functionality as the tone clock circuit pack. The IPSIs can be connected via CAT5
cable to the media server complex (via Ethernet switch) before the cutover. You can do this while the
IPSIs are working as tone clocks in the existing system. This allows you to test connectivity between the
media servers and the IPSIs before the cutover. Even though you are converting the PPN to a PN, it's a
good idea to install the IPSIs in the PPN and test connectivity ahead of time. You then re-install the IPSIs
in the new carrier(s) after they are installed.
This stage is service affecting for standard reliability configurations. As each IPSI-equipped PN is
worked on, it is out of service while the circuit packs are being changed. Service impact can be
minimized for high or critical reliability configurations by only working on the circuit packs in the
standby carriers (MCC) or cabinets (SCC).
Converting the processor port network to a
port network
This stage consists of replacing the processor carrier A in the PPN with a new expansion control carrier
(J58890AF-2 L13). If the PPN has duplicated control carriers (cabinets if SCC), then you also must
replace carrier B with a new port carrier (cabinet if SCC).
If you replaced the EIs and maintenance circuit packs and replaced the tone clock with an IPSI in the old
control carrier, you must reinsert them into the new control carrier. You do not need to reprogram the
IPSI. If you have a center stage switch or ATM, you must move the EIs to positions A01 and B02 (if
critical reliability).
You must install and configure the media servers, transfer the translations, and upgrade the existing EPNs
before performing this stage.
