Abstract: An interconnect system connects two drawer management cards (DMCs) of a drawer. The drawer contains a plurality of independent nodes. The nodes are managed by at least two DMCs. Thus, if one of the DMCs fails, the other DMC can take over and manage the drawer. In one embodiment of the invention, the nodes within the drawer are managed through an Intelligent Platform Management Bus (IPMB). The other field replaceble units (FRUs) or hardware components in the drawer, such as fans, power supplies, etc., may be managed using an Inter Integrated Circuit bus (I2C). The first and second DMCs are interconnected with each other within a chassis of the drawer. The two DMCs are also interconnected with the management channels (e.g., buses) of the drawer. During power up, the first DMC and the second DMC on the drawer may determine, whether the DMC's are interconnected (or not). The DMCs then decide each of their roles (i.e., determining which DMC should be in an active state and which DMC should be in a standby state). Thus, by interconnecting (e.g., the IPMBs and I2Cs of) the two DMC's, both of the DMC's are able to manage nodes on a drawer and the drawer is allowed to operate uninterrupted in the event of a failure or inoperativeness of one of the DMCs.

Abstract: A system and method is provided to allow a computer network system to keep a device in a powered off state over a power cycle. A service processor stores the power state information or power mask corresponding to the field replaceable unit (FRU) slots in a non-volatile storage location. As a result, after the system has been powered off and on, the power mask information is retained. Accordingly, a hotswap controller may then retrieve the power mask from storage to determine whether a given FRU should be powered on or kept in a powered off state. Depending on the power mask, the service processor will not power on the FRU if the power mask indicates that the device should remain in a powered off state. A management entity may update the power mask information depending on predetermined parameters or the condition of the FRU. As a result, a power mask may be maintained for several power cycles to keep a device in a powered off state.

Abstract: A system and method is provided for a computer network system to allow a device associated with a client-ID to be replaced without requiring the network system to reconfigure the client-ID information. The client-ID configuration information can be associated or tied to a slot or holder for a network device, rather than the network device itself. For example, the client-ID configuration information may be tied to an FRU holder, such as a Compact Peripheral Component Interconnect (CPCI) slot, and not the FRU itself. The client-ID configuration information is managed by a central resource. Accordingly, when the network device is replaced with a new device, the client-ID can be assigned from this central resource. The central resource may be a service processor or an alarm card. The service processor may access a storage device to retrieve the client-ID and transmit it to an FRU. Thus, when the FRU is replaced, this client-ID information is downloaded from the service processor by the new FRU. As a result, the need to reconfigure the client-ID information in the event a network device is replaced can be avoided.
