Figure 28: S8700-series fiber-PNC in a standard reliability configuration

Figure notes:

1.The Administration PC accesses the

S8700-series Server over the corporate data network.

2.Corporate IP network.

3.Corporate IP network interface. The Ethernet 4 link from the S8700 to the data network.1

4.Two S8700s are always present. One server is in active mode, and the other server is on standby.

5.Duplication interface, default Ethernet 2. The dedicated Ethernet connection between the S8700-series Servers.

6.Services interface, default Ethernet 1. The server's dedicated Ethernet connection from the S8700 to a laptop computer (active only during on-site administration or on-site maintenance).

7.Network control A interface, default Ethernet 0. The server's Ethernet connection to one or two Ethernet switches. This Ethernet link carries the control signals for the PNs.

8.Ethernet switch. At least one Ethernet switch is required to support the control network. If many PNs are present, two Ethernet switches can be daisy-chained together to provide sufficient Ethernet connections to the IPSI boards in the PNs.

9.UPS. Keeps the S8700-series Servers and the Ethernet switches functional during brief power outages.

10.Port networks.

11.IPSI. The IPSI circuit pack carries the control network signals to the PNs, and provides tone clock functionality.

12.Bearer connectivity over Center Stage Switch or ATM.

1.The Ethernet connection to the corporate network in this figure is a nondedicated network. IP addresses for the various components of the S8700-series fiber-PNC configuration must be administered to prevent conflicts with other equipment that shares the network. In the default S8700 fiber-PNC configuration, all other Ethernet connections operate on their own closed LANs.
