Abstract

A data processing unit, which is operatively coupled within a data center network, is configured to output a first visual indicia, a second visual indicia and a third visual indicia. The first visual indicia includes a set of light outputs, each of which is associated with a port status of a network port of the data processing unit. The second visual indicia includes a set of graphical outputs produced by a display screen, each of which is associated with an operating status of the data processing unit. The third visual indicia includes a set of backlight outputs produced by the display screen, each of which is associated with the operating status of the data processing unit.

2. The apparatus of claim 1, wherein the data processing unit is at least one of an access switch, a router, a server or a data storage device.

3. The apparatus of claim 1, wherein the data processing unit includes a light emitting diode configured to produce the plurality of light outputs of the first visual indicia, each light output from the plurality of light outputs having a characteristic associated with the port status.

4. The apparatus of claim 1, wherein the port status of the network port is associated with at least one of a link activity of the network port, a mode of operation of the network port or a speed of data transmission via the network port.

5. The apparatus of claim 1, wherein the operating status of the data processing unit includes at least one of a fan fault, a thermal fault or a power supply fault.

17. The apparatus of claim 1, wherein the display screen is configured to produce the first backlight output and the second backlight output substantially simultaneously.

18. The apparatus of claim 1, wherein the display screen is configured to produce the first backlight output at a frequency that is out of phase with a frequency with which the second backlight output is produced.

19. The apparatus of claim 1, wherein the first portion of the display screen is distinct from the second portion of the display screen.

6. An apparatus, comprising:

a data processing unit configured to be operatively coupled within a data center network, the data processing unit including;

a network port configured to operatively couple the data processing unit to another data processing unit associated with the data center network;

a plurality of light emitting diodes, each light emitting diode from the plurality of light emitting diodes configured to produce an output having a characteristic associated with a status of the network port, at least one light emitting diode from the plurality of light emitting diodes being indicative of a Power over Ethernet (PoE) status of the data processing unit;

a display screen having a first portion and a second portion different from the first portion, the first portion configured to produce a first backlight output associated with a first location of the data processing unit, the second portion configured to produce a second backlight output associated with a second location of the data processing unit, a characteristic of the second backlight output different from a characteristic of the first backlight output, the display screen configured to produce the first backlight output and the second backlight output substantially simultaneously, the first portion of the display screen being distinct from and substantially surrounded by the second portion of the display screen; and

a display controller configured to control the first backlight output in response to a change in an operating status of a component adjacent the first location of the data processing unit.

7. The apparatus of claim 6, wherein the change in the operating status of the component is associated with at least one of a fan fault, a thermal fault or a power supply fault.

8. The apparatus of claim 6, wherein the display controller is configured to adjust at least one of a color of the first backlight output, a brightness of the first backlight output or a contrast of the first backlight output.
