Making External Clock Connections

The DB-15 connector labeled Ext Clocks on the faceplate of the SCM connects two external sources for a high-stability clock (primary and redundant). These inputs are 1.544 MHz or 2.048 MHz. In addition, one of the trunk or circuit line inputs can also serve as a source of timing for the node. If you do not select a clock source, the clock source is the internal IGX clock.

Two separate clock inputs exist. The primary clock source is A, and the secondary clock source is B. One or both of these can be either 1.544 Mbps or 2.048 Mbps. For a list of connector pin assignments, see Appendix C, “Cabling Summary.”

Attaching Peripherals

A network must have at least one control terminal (or a Cisco WAN Manager workstation if you wish to collect statistics) attached, along with a network printer for printing out the status of the system. The SCM has three ports for attaching peripherals to an IGX node. These ports are Control Terminal, LAN AUI, and AUX port.

For the Cisco TAC to perform remote troubleshooting, a modem must connect to the network. This is a requirement for all Cisco service plans. The following sections provide procedures for attaching peripherals to the IGX node. Be sure to read the manufacturers’ literature to ensure that the equipment is ready before attempting to connect it to the IGX node.

Connecting a Single Network Management Station

To use network management, at least one node in a Cisco WAN switching network running Release 7.2 or higher software must have a Cisco WAN Manager workstation connected. The workstation connects to the AUI Ethernet LAN port on the SCM.

The Cisco WAN Manager workstation can be used to configure and maintain all nodes in a network.

For instructions on using the Cisco WAN Manager workstation, see the

Cisco StrataView Plus Operations Guide.

If only a single NMS station is connected and the network is relatively small, you can use a serial

EIA/TIA232 port—the Control Terminal port.

The appendix titled “Peripherals Specifications” lists the control terminals supported by the IGX 8410 node and the configuration settings. Appendix C, “Cabling Summary” has the pin assignments for the IGX 8410 control terminal port.
