1. A computer system configured to connect to a network, the computer system comprising:
- a connection framework configured to receive at least two field replaceable support units and at least one field replaceable system unit;
wherein the connection framework is configured to store a set of network identities for at least predetermined ones of the field replaceable units;
wherein each field replaceable support unit is configured to store a copy of the set of network identities for at least predetermined ones of the field replaceable units; and
wherein, where a first one of the field replaceable support units is operable in the connection framework and a second field replaceable support units is powered up, the first field replaceable support unit is configured to determine whether the network identities stored in the second field replaceable support unit are equivalent to the network identities stored in the connection framework.

Abstract
Network identities for components (e.g., server blades) of a multi-domain computer system (e.g., a server blade system) are stored in a connection framework (e.g., a carrier for the server blades) and copies thereof are stored in two or more support units (e.g., service processors for the carrier). These multiple copies can then be used to ensure the integrity of network identities that are allocated to the system units by the support units.

14. A method of connecting a computer system to a networks wherein the computer system includes a connection framework for receiving at least two field replaceable support units and at least one field replaceable system unit, the method comprising:
-
storing a set of network identities for at least predetermined ones of the field replaceable units in the connection framework; storing, in said field replaceable support units, a copy of the set of network identities for at least predetermined ones of the field replaceable units; and where a first one of the field replaceable support units is operable in the connection framework and a second field replaceable support units is powered up, determining whether the network identities stored in the second field replaceable support unit are equivalent to the network identities stored in the connection framework. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A blade server system configured to connect to a network, the blade server system comprising:
-
a carrier configured to receive a plurality of field replaceable units; a first field replaceable support unit and a second field replaceable support unit received in the carrier; and one or more field replaceable server blades received in the carrier; wherein the carrier is configured to store a set of network identities for at least predetermined ones of the field replaceable units; wherein each field replaceable support unit is configured to store a copy of the set of network identities for at least predetermined ones of the field replaceable units; and wherein, in response to powering up the second field replaceable support unit, the first field replaceable support unit is configured to determine whether the network identities stored in the field replaceable support units are equivalent to the network identities stored in the carrier. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A computer system configured to connect to a network, the computer system comprising:
-
a connection framework configured to receive a plurality of field replaceable units; a first field replaceable support unit and a second field replaceable support unit received in the connection framework; and one or more field replaceable system units received in the connection framework; wherein the connection framework is configured to store a set of network identities for at least predetermined ones of the field replaceable units; wherein each field replaceable support unit is configured to store a copy of the set of network identities for at least predetermined ones of the field replaceable units; and wherein, in response to powering up the second field replaceable support unit, the first field replaceable support unit is configured to determine whether the network identities stored in the field replaceable support units are equivalent to the network identities stored in the connection framework.
