Switch ground
Dell EMC recommends you ground your switch. Use the N2200-ON Series switch in a common bond network (CBN).
Connect the grounding cables as described in
NOTE:
For an AC-powered switch, although the third conductor of the AC power cable provides a ground path, Dell
EMC recommends grounding your switch with a dedicated ground wire.
NOTE:
For a DC-powered switch, the only way to safely ground your switch is to attach a dedicated ground wire. The
ground lug kit ships in a plastic bag that is placed with the other accessories inside the shipping box. To ground your
switch, first attach the ground lug to the switch using the screws. Then attach the DC ground wire to the ground lug.
Fans and airflow
The N2200-ON Series switch fans support two airflow options: normal and reverse.
NOTE:
Reverse airflow is only supported on the N2224X-ON and N2248X-ON AC switches.
Fan combinations
Fan installation is completed as part of the factory install based on stock keeping unit (SKU) type. The N2200-ON Series switch has SKUs
that support the following configurations:
•
AC or DC PSU with fan airflow from the I/O to the PSU—the red indicator on the handle is the normal airflow direction.
•
AC PSU with fan airflow from the PSU to the I/O—the blue indicator on the handle is the reverse airflow direction.
Order the fans suitable to support the ventilation at your site. Use a single type of airflow fan in your switch. Do not mix reverse and
normal airflows in a single N2200-ON Series switch.
For proper ventilation, position the switch in an equipment rack or cabinet with a minimum of 5 inches (12.7 cm) of clearance around the
exhaust vents. When you install two N2200-ON switches near each other, to permit proper airflow, position the two switches at least 5
inches (12.7 cm) apart. The fan speed varies based on internal temperature monitoring. The N2200-ON Series switch never intentionally
turns off the fans.
For more information, see Fans.
Power
To connect the switch to the applicable power source, use the appropriate power cable. An AC power cable is included with each PSU. If
you optionally order DC PSUs, they ship with a DC power cable.
When installing AC or DC switches, follow the requirements of the National Electrical Code, ANSI/NFPA 70, where applicable.
The switch is powered-up when you connect the power cable between the switch and the power source. For more information, see
Power
supplies.
NOTE:
This equipment must be earthed. Connect the power plug to a properly wired earth ground socket outlet.
CAUTION:
Always disconnect the power cable before you service the power slots. The switch has multiple power cables.
Before servicing, ensure that all power cables are disconnected.
CAUTION:
On an AC switch, use the power cable as the main disconnect device. Ensure that the socket-outlet is located
and installed near the equipment and is accessible.
NOTE:
Software controls the module power. You do not see module LEDs when the switch powers up in ONIE.
Storing components
If you do not install your N2200-ON Series switch and components immediately, properly store the switch and all components using these
guidelines:
•
Storage location temperature must remain constant. The storage range is from -40°C to 70°C (-40°F to 158°F).
