Abstract

A network (10) includes a repeater (12) that can service data devices that operate using different communications protocols. The data devices (18, 20, 22) couple to the ports (34) of the repeater (12), and operate using a first communications protocol in a first domain (14). The data devices (26, 28, 30) also couple to the ports (34) of the repeater (12) and operate using a second communications protocol in a second domain (16). Information on the operation of a port (34) may be displayed using one port indicator (202) or two port indicators (300, 302).

Claims

1. A repeater for exchanging data among a plurality of data devices, comprising:

a plurality of ports positioned along a first line and operable to couple to the data devices, each port operable to exchange data with an associated data device in a selected one of a first associated data device in a selected one of a first domain and a second domain;

a plurality of port indicators positioned along a second line parallel to the first line, each port indicator associated with one of the ports, each port indicator operable to display information on its associated port; and

a mode indicator having a first mode and a second mode, the first mode signifying that the port indicators display information on ports operating in the first domain, the second mode indicating that the port indicators display information on ports operating in the second domain.

2. The repeater of claim 1, wherein:

the first domain comprises data devices operating at a first data rate; and

the second domain comprises data devices operating at a second data rate.

3. The repeater of claim 1, wherein the mode indicator comprises:

a first mode indicator operable to indicate the first mode; and

a second mode indicator operable to indicate the second mode.

4. The repeater of claim 1, wherein the mode indicator comprises:

a first mode indicator operable to indicate the first mode;

a second mode indicator operable to indicate the second mode; and

a third mode indicator operable to indicate alternating over time between the first mode and the second mode.

5. The repeater of claim 1, comprising a mode switch operable to lock on one of a selected first mode and second mode.

6. The repeater of claim 1, wherein the information comprises activity information.

7. The repeater of claim 1, wherein the information comprises link information.

8. A method for displaying information on a plurality of ports of a repeater, the ports being positioned along a first line, each port operable to exchange data with an associated data device in a selected one of a first domain and a second domain, the method comprising:

disposing a plurality of port indicators on the repeater, the port indicators positioned in a second line parallel to the first line, each port indicator associated with one of the ports;

selecting one of a first mode and a second mode, the first mode signifying that the port indicators display information on ports operating in the first domain, the second mode signifying that the port indicators display information on ports operating in the second domain; and

displaying information in response to the selected mode.

9. The method of claim 8, wherein the step of disposing comprises positioning the port indicators along a line.

10. The method of claim 8, wherein the step of selecting comprises automatically alternating over time between the first mode and the second mode.

11. The method of claim 8, wherein the step of selecting comprises activating a mode switch to lock on one of a selected first mode and second mode.

12. The method of claim 8, wherein the information comprises activity information.

13. The method of claim 8, wherein the information comprises link information.

14. A repeater for exchanging data among a plurality of data devices, comprising:

a plurality of ports positioned along a first line and operable to couple to the data devices, each port operable to exchange data with an associated data device in a selected one of a first domain and a second domain;

a plurality of first port indicators positioned along a second line parallel to the first line, each first port indicator associated with one of the ports, each first port indicator operable to display information when its associated port operates in the first domain; and

a plurality of second port indicators positioned along a third line parallel to the first line, each second port indicator associated with one of the ports, each second port indicator operable to display information when its associated port operates in the second domain.

15. The repeater of claim 14, wherein:

the first domain comprises data devices operating at a first data rate; and

the second domain comprises data devices operating at a second data rate.

16. The repeater of claim 14, wherein the information comprises activity information.

17. The repeater of claim 14, wherein the information comprises link information.

18. The repeater of claim 14, wherein:

the first line is disposed between the second line and the third line.

19. A system for exchanging data among a plurality of data devices, comprising:

a first domain having data devices operating at a first communications protocol;

a second domain having data devices operating at a second communications protocol;

a plurality of ports positioned along a first line and operable to couple to the data devices, each port operable to exchange data with an associated data device in a selected one of the first domain and the second domain; and

a plurality of port indicators positioned along a second line parallel to the first line, each port indicator associated with one of the ports, each port indicator operable to display information on its associated port.

20. The system of claim 19, comprising a mode indicator having a first mode and a second mode, the first mode signifying that the port indicators display information on ports operating in the first domain, the second mode indicating that the port indicators display information on ports operating in the second domain.

21. The system of claim 19, wherein the port indicators comprise:

a plurality of first port indicators, each first port indicator associated with one of the ports, each first port indicator operable to display information on its associated port operating in the first domain; and

a plurality of second port indicators, each second port indicator associated with one of the ports, each second port indicator operable to display information on its associated port operating in the second domain.

22. The system of claim 19, wherein the information comprises activity information.

23. The system of claim 19, wherein the information comprises link information.

24. A repeater for exchanging data among a plurality of data devices, comprising:

a plurality of ports positioned along a first line and operable to couple to the data devices, each port operable to exchange data with an associated data device in a selected one of a first domain and a second domain;

a plurality of first port indicators positioned along a second line parallel to the first line, each first port indicator associated with one of the ports, each first port indicator operable to display information when its associated port operates in the first domain; and

a plurality of second port indicators, each second port indicator associated with one of the ports, each second port indicator operable to display information when its associated port operates in the second domain.

25. The repeater of claim 24, wherein:

the first domain includes data devices operating at a first data rate; and
