INSTALLING THE SWITCH
61
Figure 3-11 Removing the Module
Note:
•
Pull the module out of the slot gently.
•
Install the filler panel in the empty slot to allow for adequate airflow.
3.5. Grounding the Switch
Connect the PGND to the grounding lug of the rack and then connect the grounding lug to the
grounding bar of the equipment room.
Notes
•
The sectional area of the grounding wire should be determined according to the possible
maximum current. Cables of good conductor should be used.
•
Do not have bare wires exposed
•
Grounding resistance: Less than 1 ohm.
Note:
•
To guarantee the security of the person and the device, the switch must be grounded
properly. The grounding resistance between the chassis and the ground should be less
than 1ohm.
•
The maintenance personnel should check whether the AC socket is reliably connected
to the protective ground of the building. If not, the maintenance personnel should use a
protective earth conductor from the AC outlet protective earth terminal to the building
protective earth.
•
The power socket should be installed near the device and easily accessible.
•
The AC power should be connected to an output socket with a ground connection using
a power cord.
•
When installing the switch, connect the grounding first and disconnect it last.
3.6. Connecting Cables
Notes
•
Distinguish single-mode and multi-mode fiber-optic cables and ports.
•
Avoid a small bend radius at the connector.
