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 S8700 Series Manual

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.
If you want to cutover and have the S8700 or S8710 Media Server control the existing EPNs
while you convert the PPN, you first must power down the PPN and then enable the IPSIs from
the S8700 or S8710 Media Server. Do this only if the customer wants to minimize downtime. If
the PPN also contains the switch node carrier(s), then powering down the PPN also takes down
the center stage switch (CSS).
