1000Base-X or 10/100/1000Base-T connections provided. However, the 1000Base-X fiber connection has priority
over the 10/100/1000Base-T copper connection. If a link is detected on the 1000Base-X interface, the 10/100/
1000Base-T connection will be disabled.
NOTE: Dell tests and supports optics offered through Dell W-Series products within Dell controller systems. Third party optics are
not tested or supported; therefore, Dell does not guarantee proper functionality of third party optics when used in a Dell controller.
10/100/1000Base-T (RJ-45) Ports
The W-7200 controller is equipped with two 10/100/1000Base-T copper ports. Gigabit Ethernet uses all eight
wires and each pair is used in a bi-directional fashion, meaning the same pairs are used for both data transmission
and reception. Figure 2 illustrates the CAT-5 pin-out found on an RJ-45 connector. The CAT-5 pin-out pairs the
following pins on a 10/100/1000Base-T Gigabit Ethernet port: 1/2, 3/6, 4/5, and 7/8.

Fan Tray
CAUTION: The W-7200 controller is equipped with a field-replaceable, hot-swappable fan tray. Each fan tray features four
individual fans that pull air through the chassis from the front through to the rear. Each fan tray can tolerate the failure of a single
fan while maintaining a safe operating temperature for the controller
CAUTION: The W-7200 controller is not compatible with fan trays from other Dell hardware platforms.
Hot Swapping
Hot swapping allows you to replace a failed fan tray, making it unnecessary to shut down the W-7200 controller
during the replacement procedure.

Power Supply
CAUTION: Never insert or remove a power supply while the power cord is connected. Verify that cord has been disconnected
from the power supply before installation or removal.
The W-7200 series controller’s Power Supply adapts electrical power for use with the W-7200. The chassis has
two slots that can hold individual power supplies to support load sharing, redundancy, and fault tolerance. The
W-7200 controller comes equipped with a single 350W AC power supply.
The W-7200 controller is shipped with one hot-swappable, field-replaceable, AC power supply and one blank face
plate. The included power supply is installed in the slot PSU 0, while slot PSU 1 has a blank face plate covering
the opening. The controller can operate with one or two active power supplies, depending on the demands of your
configuration.
Load Sharing
Load sharing occurs when more than one power supply of the same rating is installed in the W-7200 controller
and turned on. Load sharing divides the total power load of the controller among all available power supplies.
Since the power supplies work together, the effective power capacity of the controller is increased with each
additional power supply.
Redundancy
With power redundancy, the W-7200 controller can continue normal operation even when a power supply fails or
is turned off. When multiple power supplies are installed, if one becomes unavailable (fails, or is turned off or
removed) the remaining power supplies will attempt to provide full power for the device. If the device’s total
power load does not exceed the combined rated output of the remaining, operational power supplies, the
controller will continue to operate.
Hot Swapping
Hot swapping allows you to replace one failed power supply while the others provide full power. This makes it
unnecessary to shut down the W-7200 controller during the replacement procedure.
Hot swapping is supported only when power redundancy is in effect. This requires that after the target power
supply is removed, the device’s total power load does not exceed the combined rated output of the remaining
power supplies

Modules
The 350W power supply is an autosensing, load-sharing, redundant power supply module that supports an input
voltage of 100 VAC to 240 VAC. Each power supply has a country-specific power cord for connection to an AC
power outlet.
