LED Description
LINK
z
OFF means no link is present;
z ON means a link is present.
ACT
z OFF means no data is being transmitted or received.
z
Blinking means data is being transmitted and/or received.
The following figure shows the FIC-8SAE panel:
Figure 4-70 FIC-8SAE front panel
On the FIC-8SAE panel, each link corresponds to a LED. ON means a link is present; blinking means
data is being transmitted and/or received.
Interface cable
The FIC-SAE modules use synchronous/asynchronous serial interface cables with DB-28 connectors.
Before connecting an FIC-SAE module, identify the line properties and then select the proper interface
cable from the following ten cable options:
z
V.24 (RS232) DTE cable: DB-25 plug at the network end
z
V.24 (RS232) DCE cable: DB-25 receptacle at the network end
z
V.35 DTE cable: 34PIN plug at the network end
z
V.35 DCE cable: 34PIN receptacle at the network end
z
X.21 DTE cable: DB-15 plug at the network end
z
X.21 DCE cable: DB-15 receptacle at the network end
z
RS449 DTE cable: DB-37 plug at the network end
z
RS449 DCE cable: DB37 receptacle at the network end
z
RS530 DTE cable: DB-25 plug at the network end
z
RS530 DCE cable: DB25 receptacle at the network end
All these cables use a DB-28 connector to connect the router, but the connector at the network end
varies with the type of the to-be-connected network.
