CAUTION:
Avoid bending fiber-optic cable beyond its minimum bend radius. An arc
smaller than a few inches in diameter can damage the cable and cause problems
that are difficult to diagnose.
CAUTION:
Do not let fiber-optic cable hang free from the connector. Do not allow
fastened loops of cable to dangle, which stresses the cable at the fastening point.
Step 5: Connect Ground and Power Cables
Depending on your configuration, your device uses either AC or DC power supplies.
Perform the appropriate procedures for each power supply in your device:
■
Connect the Grounding Cable on page 15
■
Connect Power to an AC-Powered Ethernet Appliance on page 16
■
Connect Power to a DC-Powered Ethernet Appliance on page 17
Connect the Grounding Cable
1.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to an approved site ESD grounding point. See the instructions
for your site.
2.
Connect the grounding cable to a proper earth ground.
3.
Verify that a licensed electrician has attached the cable lug provided with the
Ethernet appliance to the grounding cable.
4.
Make sure that grounding surfaces are clean and brought to a bright finish before
grounding connections are made.
5.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and
connect the strap to one of the ESD points on the chassis. For more information
about ESD, see the
IBM Ethernet Appliance J58S Hardware Guide
.
6.
Place the grounding cable lug over the grounding point. The left pair is sized for
M6 screws, and the right pair is sized for UNC 1/4-20 screws.
7.
Secure the grounding cable lug to the grounding point, first with the washers,
then with the screws.
8.
Verify that the grounding cabling is correct, that the grounding cable does not
touch or block access to device components, and that it does not drape where
people could trip on it.
