Figure 1.2 – Click 340/341/342 Physical Features
The following is a list of the physical features included on the managed Ethernet switches:
˽ Diagnostic/status indicators – Important information is displayed directly on the de-
vice. Each port has two LEDs. The top LED always indicates LNK/ACT, and the bottom
LED indicates the data transmission rate.
˽ Diagnostic and status LEDs – Two status and diagnostic LEDs are available for the
supply voltage and for each port.
˽ Mini-DIN RS-232 (V.24) – RS-232 (V.24) interface in Mini-DIN format for local con-
figuration via the serial interface.
˽ Alarm contact/functional earth ground – The floating alarm contact and the optional
functional earth ground can be connected here via the pluggable screw terminal.
˽ Supply voltage connection – The supply voltage can be connected redundantly via the
4-pos. pluggable screw terminal as an option.
The figure below shows the physical dimensions of the Click 340/341/342 module (see
Figure 1.3).
