Connecting to GBIC Module Ports
When connecting the ports on the Catalyst 2950G-24-EI-DC and
Catalyst 2950ST-24 LRE 997 switches to other devices, follow these guidelines:
Caution
To comply with the intrabuilding lightning surge requirements, intrabuilding
wiring must be shielded, and the shield for the wiring must be grounded at both
ends.
Caution
The Catalyst 2950G-24-EI-DC or Catalyst 2950ST-24 LRE 997 switch is suitable
only for intrabuilding or nonexposed wiring connections.
Connecting to 1000BASE-X GBIC Module Ports
Caution
Do not remove the rubber plugs from the GBIC module port or the rubber caps
from the fiber-optic cable until you are ready to connect the cable. The plugs and
caps protect the GBIC module ports and cables from contamination and ambient
light.
After installing the 1000BASE-X GBIC in the GBIC module slot, follow these
steps:
Step 1
Remove the rubber plugs from the GBIC module port, and store them for future
use.
Step 2
Insert the SC connector in the fiber-optic receptacle (see
Figure 3-38
).
