Figure 60 RS-530 DCE cable

Connecting the cable

CAUTION:

• Never stare into an open fiber Ethernet port, because invisible rays might be emitted from the port.

• Cover the dust cover if no optical fiber connector is connected to the fiber Ethernet port.

To connect the interface cable:

1. Examine port type of the peer device and choose the synchronous serial interface cable of correct

type.

2. Plug the DB-28 end of the synchronous serial interface cable into the DB-28 interface of the SAE

interface module.

3. If the WAN uses DDN line, connect the cable to the port of CSU/DSU.

4. Examine the LINK LED on the SAE panel.

{ If the LED is on, a link is present.

{ If the LED is off, a fault has occurred on the link and signal is out of synchronization. In this case,

examine the link.
