LED
Description
LINK
OFF means no link is present; ON means a link is present.
ACT
OFF means no data is being transmitted or received; blinking
means data is being received or/and transmitted.
MIM-8SAE panel is shown in the following figure:

MIM-8SAE panel
On MIM-8SAE module, each link corresponds to a LED. ON means the link is
connected. Blinking means data is being transmitted or received.
3.4.4 Interface Cable
SAE modules use synchronous/asynchronous serial interface cables with DB-28
connectors for connection.
Before connecting to a port on 2SAE, confirm the line properties. There are ten cable
options depending on different line properties:
z
V.24 (RS232) DTE cable: DB-25 (male) connector at the network end
z
V.24 (RS232) DCE cable: DB-25 (female) connector at the network end
z
V.35 DTE cable: 34PIN (male) connector at the network end
z
V.35 DCE cable: 34PIN (female) connector at the network end
z
X.21 DTE cable: DB-15 (male) connector at the network end
z
X.21 DCE cable: DB-15 (female) connector at the network end
z
RS449 DTE cable: DB-37 (male) connector at the network end
z
RS449 DCE cable: DB-37 (female) connector at the network end
z
RS530 DTE cable: DB-25 (male) connector at the network end
z
RS530 DCE cable: DB-25 (female) connector at the network end
At one end of these cables is a DB-28 connector and at the other end is the connector
that varies with the port at the network side.
