Installing and Removing GBICs
Gigabit Ethernet network modules support GBIC hot-swapping. To save time, do not power down the
router and network module before installing or removing the GBIC.
Warning
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.
Statement 240
Note
GBICs from other vendors are not supported by the Cisco Gigabit Ethernet network module.

10-dB SMF optical attenuators with SC connectors (two per duplex cable) are required for distances less than 25 km (15.5
miles). Install the attenuators between the male SC connector on the cable and the female SC connector on the network
module.
