If all of the FEM Link and Duplex LEDs blink synchronously, the module has
failed.
Gigabit Ethernet Module Connectors and LEDs
The Gigabit Ethernet Module (GEM), model CSS5-IOM-2GE, contains two
1000-Mbps SFP GBICs with LC-type connectors. The GEM can use either:
•
Longwave-length SFP GBICs (CSS5-GBIC-LX). The longwave length
transceiver (1000BASE-LX) can reach 550 meters for all multimode media
types. For single-mode fiber, the distance is 5,000 meters.
•
Shortwave-length SFP GBICs (CSS5-GBIC-SX). The transceiver distance
can reach from 220 meters to 500 meters, depending on the quality of the
fiber.
Warning
Because invisible radiation may be emitted from the aperture of the port when
no fiber cable is connected, avoid exposure to radiation and do not stare into
open apertures.
