The LED Mode Switch
The SmartSwitches 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
. The 6H202-24 and the 6H262-18 have the
switch positioned near the bottom of the board. The 6H252-17 has the switch positioned near the
top of the board. The switch functionality applies no matter where on the modules the switch is
positioned. 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.
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.
NOTE
The LED mode switch does not change the function of any LEDs on an HSIM or VHSIM
installed in the 6H252-17. The GPIMs installed in the 6H262-18 will have the indications
as listed starting in
Table 4-4
.
