Connecting to Devices and Networks
This chapter provides guidelines for making physical connections between the D20 and
substation and network devices.
Cabling overview
All physical connections are made to the connectors on the rear backplane of the D20
chassis or to the front on the D20MX processor module.
D20MX front panel connectors
The D20MX front panel can have one of the following layouts:
•
Ethernet connectors (RJ45); see Figure 14.
• Front access Fiber optic connectors (ST); see Figure 15.
• Rear access Fiber optic connectors on a fiber optic daughter card; see Figure 16. The
optic daughter card can be either a D20MX dual 100 BASE-FX ST Media Interface Card
or a D20MX dual 100 BASE-FX LC Media Interface Card.
For a description of the operational status LEDs and port status LEDs, see “Front panel
