LANVIEW LEDs
The LED MODE switch is located on the front panel of the 2H252-25R as shown in
Figure 4-1
.
This switch enables the user to change the function of the port LEDs. When the LED MODE
switch is moved to the left, the LEDs indicate the receive (RX) and transmit (TX) status of the
respective fixed ports (ports 1 through 24). When the LED MODE switch is moved to the right, the
port LEDs indicate whether the respective ports are operating in the standard or full duplex mode
(FDX) and if their operating speed (SPD) is 10 or 100 Mbps.
NOTE:
The LED mode switch does not change the function of any LEDs on an installed
HSIM or VHSIM.
