To connect a Gigabit Ethernet cable to a mini-GBIC connector transceiver port:

1.

Hold the cable clip firmly but gently between your thumb and forefinger, with 
your thumb on top of the clip and your finger under the clip. (Do not depress the 
clip ejector on top of the clip.)

2.

Slide the clip into the transceiver port until it clicks into place. Because the fit is 
close, you may have to apply some force to seat the clip. Apply force evenly and 
gently, to avoid clip breakage.

To remove the cable from the transceiver port:

1.

Make sure the black transceiver ejector under the port is not pressed in; 
otherwise, when you attempt to remove the cable, the transceiver might come 
out with the cable still attached.

2.

Hold the cable clip firmly but gently between your thumb and forefinger, with 
your thumb on top of the clip and your finger under the clip.

3.

Use your thumb to gently press the clip ejector on top of the clip, down then 
forward. This action loosens the clip from the transceiver port.

4.

Gently but firmly, pull the clip from the transceiver port.
