551 Feature Description Internal/External Ports Internal: 20 4X QDR copper ports/ External: 16 4X QDR copper ports Bandwidth 4X QDR (40 Gbps) non-blocking architecture for 2.88 Tbps total bandwidth (36-port) The module includes an integrated Chassis Management Module (CMM) installed as an add-on-module inside the switch chassis. This allows installation of two (redundant) switches in the AB7000 enclosure without the loss of system management capability. Note that a dual-port InfiniBand Add-On-Card is required if redundant switches are installed. Either the RJ45 connector or the KVM connector on the front of the module can be used to connect to the integrated CMM module (see Figure 4-225). There is also an activity indicator LED for the CMM on the left-hand side of the front of the module. The reset button (lower left), pushed once, will reset the module. If held down for approximately 5 seconds it will send a signal to the CMM, which cause the CMM to return to default settings. See Chapter 4, Section 4.1 of the AB7000 User's Manual for more information on the operation of the CMM itself, including instructions on how to use both the KVM and RJ45 connections.
