Connecting the Transceiver
WARNING: Optical SFPs use a small laser to generate the fiber-optic
signal. Because invisible laser radiation may be emitted
from the aperture of the port when no fiber cable is
connected, avoid exposure to laser radiation and do not
stare into open apertures. Keep the optical transmit and
receive ports covered whenever a cable is not connected
to the port.
Connecting the Cisco MGBBX1, MFEBX1, MGBLX1,
MFEFX1, MFEL X1, MGB SX1, and MGBLH1
STEP 1 Insert the mini-GBIC SFP module with the printed side up and the
rubber port cap facing out.
STEP 2 Remove the mini-GBIC SFP module’s rubber port cap.
S
TEP 3 Connect the fiber cable’s LC connector to the mini-GBIC SFP module’s
port.
STEP 4 Connect the other end of the cable to an SFP module to verify that the
fiber connection is complete.
For the Cisco MGBBX1, use the Cisco GLC-BX-D as the downstream SFP. For
the Cisco MFEBX1, use the Cisco GLC-FE-100BX-D as the downstream SFP.
The Cisco MGBBX1 and the Cisco MFEBBX1 support upstream only.
