Enterasys Networks 2H252-25R ユーザーズマニュアル

The LED MODE switch is located on the front panel of the 2H252-25R as shown in 

. 

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.
