Physical Description
LEDs
The LEDs on the Model SW510 and the Model SW518 switches are used to monitor and diagnose
the devices. LEDs on the front panel of the switch and two LEDs on each port allow you to
identify the following information:
•
Status of the switch power supply
•
Data transmission or receive activity
•
Collision occurrence
•
Full- or half-duplex transmission
Table 2-1
describes each LED on the front panels of the switches. See
Figure 2-1
,
Figure 2-2
, and
Figure 2-3
for the locations of the LEDs.
