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.
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.
