The following table describes the LEDs on the MIM-1VT1 panel:

Table 85 Description of the LEDs on the MIM-1VT1 panel

LED	Description
LINK	ON means carrier signal is received;
	OFF means no carrier signal is received.
ACT	OFF: No data is being received and
	transmitted;
	Blinking: Data is being received and
	transmitted.

n The MIM-1VT1 module is 1U in height, occupying two slots.

Interface Cable The interface cable of MIM-1VT1 is a standard 100-ohm standard shielding cable. The connectors on the two ends use RJ 45. The following figure illustrates this type of cable.
