## Abstract

A system for the management of rack-mounted field replaceable units (FRUs) that affords the enhanced availability and serviceability of FRUs provided by blade-based systems but in a manner that accommodates different types of FRUs (e.g., in relation to form factors, functionality, power and cooling requirements, and/or the like) installed within a rack or cabinet.

## Claims

### Claim 1

A method for electrically interconnecting one or more field replaceable units (FRUs) to at least one power source and at least one communication network within a computing rack, said method comprising steps of:
receiving a first FRU of said one or more FRUs into a receiving bay of a computing rack, wherein the first FRU comprises a connector arrangement fixed adjacent a rear portion of the first FRU, and wherein the connector arrangement is electrically interconnected to at least one power port and at least one communication port of the first FRU;
interfacing, during at least a portion of the receiving, the first FRU connector arrangement with a complimentary connector arrangement fixed adjacent a rear portion of the receiving bay of the computing rack, wherein the complimentary connector arrangement is electrically interconnected to at least one power source and at least one communication network within the computing rack, and wherein the interfacing electrically interconnects the first FRU to the at least one power source and at least one communication network within the computing rack, wherein each of the first FRU connector arrangement and the complimentary connector arrangement comprises a blind-mate connector and a mechanical connector spaced from the blind-mate connector, and wherein the interfacing comprises:
contacting the blind-mate connector of the first FRU connector arrangement with the blind-mate connector of the complimentary connector arrangement to electrically interconnect the first FRU to the at least one power source and at least one communication network within the computing rack; and
contacting the mechanical connector of the first FRU connector arrangement with the mechanical connector of the complimentary connector arrangement to align the blind-mate connector of the first FRU connector arrangement with the blind-mate connector of the complimentary connector arrangement, wherein the first FRU includes an adapter that rigidly connects the blind-mate connector and the mechanical connector of the first FRU connector arrangement to a housing of the first FRU, wherein the adapter extends outwardly away from the rear portion of a housing of the first FRU to define a space between the blind-mate connector and the housing of the first FRU for passage of one or more cables or wires that are electrically connected between the first FRU and the blind-mate connector, the space being located exterior of the housing of the first FRU.

### Claim 2 (depends on 1)

The method of claim 1, wherein the contacting of the mechanical connectors occurs before the contacting of the blind-mate connectors.

### Claim 3 (depends on 1)

The method of claim 1, wherein the adapter includes an opening that receives the blind-mate connector.

### Claim 4 (depends on 1)

The method of claim 1, wherein one of the mechanical connector of the first FRU connector arrangement and the complimentary connector arrangement comprises an alignment pin, and wherein the other of the mechanical connector of the first FRU connector arrangement and the complimentary connector arrangement comprises an alignment barrel that is configured to receive the alignment pin.

### Claim 5 (depends on 1)

The method of claim 1, wherein the computing rack comprises a plurality of receiving bays arranged along at least one dimension of the computing rack, and wherein a rear portion of each of the plurality of receiving bays comprises a respective complimentary connector arrangement configured to interface with a respective first FRU connector arrangement.

### Claim 6 (depends on 1)

The method of claim 1, wherein the receiving comprises:
slidably receiving the first FRU into the receiving bay using a rail assembly of the computing rack, wherein the interfacing occurs during at least a portion of the slidably receiving.

### Claim 7 (depends on 1)

The method of claim 1, further comprising:
securing at least first and second cables between the first FRU connector arrangement and the at least one respective power port and communication port of the first FRU to electrically interconnect the first FRU connector arrangement to the at least one power port and at least one communication port of the first FRU.

### Claim 8 (depends on 1)

The method of claim 1, wherein at least one cable is secured between the complimentary connector arrangement and central management controller of the computing rack, and wherein the method further comprises:
detecting, by the central management controller via the at least one cable, a presence of the first within the computing rack upon the interfacing.

### Claim 9 (depends on 8)

The method of claim 8, further comprising after the detecting:
determining, by the central management controller, a geographical location within the computing rack of the first FRU.

### Claim 10 (depends on 1)

The method of claim 1, wherein the method further comprising steps of:
receiving a second FRU of the one or more FRUs into a second receiving bay of the computing rack, wherein the second FRU is different in at least one respect from the first FRU, wherein the second FRU comprises a connector arrangement fixed adjacent a rear portion of the second FRU, and wherein the connector arrangement is electrically interconnected to at least one power port and at least one communication port of the second FRU; and
interfacing during at least a portion of the receiving the second FRU connector arrangement with a complimentary connector arrangement fixed adjacent a rear portion of the second receiving bay of the computing rack, wherein the complimentary connector arrangement is electrically interconnected to at least one power source and at least one communication network within the computing rack, and wherein the interfacing electrically interconnects the second FRU to the at least one power source and at least one communication network within the computing rack.

### Claim 11 (depends on 10)

The method of claim 10, wherein the at least one respect comprises at least one of a form factor, a power requirement, or a cooling requirement.
