The LED Mode Switch

The DLE02-MA and the DLE52-MA have an LED mode switch, located
on the front panel, that allows the user to change the function of the
LEDs. Refer to Figure 4-1 for the location of the LED mode switch.
When the switch is in the UP position, the LEDs indicate the receive (RX)
and transmit (TX) status of the fixed ports. When the mode switch is in
the DOWN position, the LEDs indicate at what speed the applicable port
is currently operating (10 Mbps or 100 Mbps) and if the applicable port is
operating in standard or full duplex mode.
The LED mode switch does not change the function of any
LEDs on an HSIM or VHSIM installed in the DLE52-MA.
Table 4-1 provides the definitions of the LED states that occur when the
LED mode switch is in the UP position. Table 4-2 provides the definitions
of the LED states that occur when the LED mode switch is in the DOWN
position.
