Table C-3 shows the 8100-4TX MDA LEDs.
8100 Series Fiber MDAs
The 8100 Series fiber MDAs are used to make fiber-based 100 Mb/s connections
to the switch. Two versions of these MDAs are available (Figure C-4
):
• The 8100-2FX MDA uses two longwave 1300 nm SC connectors to connect
devices over 62.5/125 µm multimode fiber optic cable.
• The 8100-4FX MDA uses four longwave 1300 nm MT-RJ connectors to
connect devices over 62.5/125 µm multimode fiber optic cable.
The 8100 Series fiber MDAs are not supported on single-mode fiber cable.
Table C-3. 8100-4TX MDA LEDs
Label Type Color/State Meaning
100 100BASE-TX port status
LEDs
Green/On The corresponding port is set to operate at 100 Mb/s.
Green/Blinking The corresponding port is management disabled.
Off The link connection is bad, or there is no connection
to this port.
10 10BASE-T port status
LEDs
Green/On The corresponding port is set to operate at 10 Mb/s.
Green/Blinking The corresponding port is management disabled.
Off The link connection is bad, or there is no connection
to this port.
F Dx Full-duplex port status
LEDs
Green/On The corresponding port is in full-duplex mode.
Off The corresponding port is in half-duplex mode.
Activity Port activity LEDs Green/Blinking Indicates the network activity level for the
corresponding port. A high level of network activity
can cause LEDs to appear to be on continuously.
