LEDs
Meaning
C2 LED (green)
Line 2 (via front connector X2, connection 2) is correct.
C2 LED (flashing
green)
A module has not yet completed the initialization process.
Front connectors
X1 and X2
Connector (output) for line 1 and line 2
X1 = upper front connector; X2 = lower front connector
The LEDs EXTF, C1 and C2 do not light up if the line is interrupted when in POWER ON mode.
In this case the IM 460 identifies an unoccupied interface.

LEDs
Meaning
INTF LED (red)
Lights up if a rack number > 21 or = 0 was set.
Lights up if you have changed the rack number under voltage.
EXTF LED (red)
Lights up in the event of an external fault (line fault, for example, if a module has
not yet completed the initialization process but not when the CC is switched off)
5 VDC (green)
Power supply in the ER is correct.
DIP switch
DIP switch to set the number of the mounting rack.
Front connector
X1
Upper connector (input) for the cable from the previous interface module.
CAUTION
Modules can be damaged.
If you want to connect an ER via the IM 461-1 interface module and use a power supply
module in this ER, you might damage the modules.
Do not use a power supply module in an ER that you want to connect to the CR via the IM
461-1 interface module.
Parameter assignment for the mounting rack number
Using the DIP switch on the front panel of the module, you must set the number of the mounting
rack in which the receive IM is installed. The permitted range is 1 to 21.
Setting/changing the number
Proceed as follows:
1. Set the power supply module in the CR to the position (Output voltage 0 V).
2. Enter the number using the DIP switch.
3. Switch the power supply module on again.
Interface modules
6.3 Interface modules IM 460-1 (6ES7460-1BA01-0AB0) and IM 461-1 (6ES7461-1BA01-0AA0)
