4-2 Troubleshooting
The LED MODE switch is located on the front panel of the 2H253-25R 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.
Table 4-1 describes the LED indications and provides recommended actions as appropriate.
Refer to the HSIM or VHSIM user’s guide for a description of the HSIM or VHSIM LED
indications.
