LINK (Link Status/Disabled).
On Green when the corre-
sponding port has a valid phys-
ical link and a signal is present.
Under normal conditions, this
LED should always be on when
a cable is connected.
TX (Transmit). On Green when
the corresponding port is trans-
mitting data.
RX (Receive). On Green when
the corresponding port is
receiving data.
This Gigabit Ethernet module
includes one row of LEDs for each
port. The LEDs for a given port dis-
play in the row labeled with the
port number. Definitions for the
LEDs are given below.

GSX-K sm
Module Label. This label will indicate
the GSX-K-FM/FS/FH-2W type. It
will read either GSX-K mm (multimode
cable), GSX-K sm (intermediate-reach
single mode cable), or GSX sm K
long reach (long-reach single-mode
cable).
SC connectors will be color
coded to indicate multimode
(Black) or intermediate-reach
single mode (Blue).
CLASS 1 LASER PRODUCT
Warning Label. This label indicates
that the module contains an optical
transceiver.
Module
LEDs
OK1 (Hardware Status). On
Green when the module has
passed diagnostic tests success-
fully. On Red when the hardware
has failed diagnostics.
OK2 (Software Status). Blinking
Green when the module soft-
ware was downloaded success-
fully and the module is
communicating with the MPX.
Blinking Red when the module is
in a transitional state. On solid
Red if the module failed to
download software from the
MPX.
