High Or Critical Reliability Configuration (Mcc1) - Avaya S8700 Series Manual

High or critical reliability configuration (MCC1)

To set up a high or critical reliability configuration:
Note:
You can replace the maintenance circuit pack with the TN775D Maintenance
Note:
(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
networks
Note:
Not every port network requires an IPSI circuit pack.
Note:
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.
Note:
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
Ribbon Cable Connector
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.
