Avaya S8500 - High or Critical Reliability Configuration (MCC1)

Upgrading and administering the existing hardware
Migrating to the Avaya S8700 or S8710 Media Server 61
June 2004
High or critical reliability configuration (MCC1)
NOTE:
You can replace the maintenance circuit pack with the TN775D Maintenance (EPN) (if
necessary) and the TN2182 Tone Clock circuit packs with the TN2312BP Internet
Protocol Server Interface (IPSI-2) circuit packs and program them ahead of time. All the
circuit packs being replaced are hot-swappable, so you do not need to power down the
PNs or the carrier.
These procedures assume that the tone-clock and maintenance circuit packs are in the A and B carriers. If
one of them is in the E or D rather than B carrier, then the ribbon cable is not necessary.
1 Determine which PNs get the IPSI circuit packs. See Determining IPSI placement in port
networks on page 57.
NOTE:
Not every port network requires an IPSI circuit pack.
2 Type list cabinet and press Enter to determine which port networks have TN2182 Tone Clock
circuit packs and in which media gateway they are in.
3 Type status port-network number where number is the number of the port network and press
Enter to determine the active tone clock.
4 If needed, type set tone cabinet carrier where cabinet is 1-64 and carrier is A-E and press Enter
to make the tone clock in the B carrier active.
5 Remove the TN2182 Tone Clock circuit pack from the standby carrier (A) and place it in an
antistatic carrier.
NOTE:
If present, do not remove the TN771 Maintenance/Test circuit pack.
6 Remove the TN775B/C Maintenance/Test circuit pack from standby carrier (A) and place it in an
antistatic carrier.
7 Insert the TN2312BP Internet Protocol Server Interface (IPSI-2) circuit pack part way into the
TONE-CLOCK slot on the standby carrier (A).
8 With the red line on the bottom (pin 1), attach one end of the short ribbon cable to the connector
on the component side of the circuit pack.
9 Push the tabs on the ends of the connector inward to lock the connector in place. See Figure 4,
Ribbon Cable Connector, on page 59.
10 Thread the ribbon through the slot on the front panel.
11 Insert the TN775D Maintenance (EPN) circuit pack part way into the MAINTENANCE slot in
carrier A.
12 Attach the other end of the short ribbon cable to the top connector on the component side of the
circuit pack (red line on the bottom). See Figure 5, Duplex Reliability Ribbon Cable Connection,
on page 60.
13 Push the tabs on the ends of the connector inward to lock the connector in place.
14 Thread the ribbon through the slot on the front panel.
15 Fully insert the TN2312BP Internet Protocol Server Interface (IPSI-2) circuit pack only.
