66 IBM BladeCenter PS703 and PS704 Technical Overview and IntroductionFigure 2-21 SOL service processor to AMM connectionBladeCenter components are configured for SOL operation through the BladeCenter AMM.The AMM also acts as a proxy in the network infrastructure to couple a client running a Telnetor SSH session with the management module to an SOL session running on a blade server,enabling the Telnet or SSH client to interact with the serial port of the blade server over thenetwork.Because all SOL traffic is controlled by and routed through the AMM, administrators cansegregate the management traffic for the BladeCenter unit from the data traffic of the bladeservers. To start an SOL connection with a blade server, follow these steps:1. Start a Telnet or SSH CLI session with the AMM.2. Start a remote-console SOL session with any blade server in the BladeCenter unit that isset up and enabled for SOL operation.You can establish up to 20 separate web-interface, Telnet, or SSH sessions with aBladeCenter AMM. For a BladeCenter unit, this step enables you to have 14 simultaneousSOL sessions active (one for each of up to 14 blade servers) with six additional CLI sessionsavailable for BladeCenter unit management.With a BladeCenter S unit you have six simultaneous SOL sessions active (one for each ofup to six blade servers) with 14 additional CLI sessions available for BladeCenter unitmanagement. If security is a concern, you can use Secure Shell (SSH) sessions, orconnections made through the serial management port that is available on the AMM, toestablish secure Telnet CLI sessions with the BladeCenter management module beforestarting an SOL console-redirect session with a blade server.SOL has the following requirements: An Ethernet switch module or Intelligent Pass-Thru Module must be installed in bay 1 of aBladeCenter (SOL does not operate with the I/O module in bay 2). SOL must be enabled for those blades that you want to connect to with SOL.BCM5709GigabitEthernetEthernet switchesin chassis bays 1and 2BCM5387EthernetswitchPhy1Gb100MbCPU0 CPU1FSPP7IOCI/O hubExternal 1 GbEthernet connections(production network)AdvancedManagementModule(redundant pair)External 100 MbEthernet connections(managementnetwork)InternalmanagementnetworkSOL trafficProduction trafficCPU 0
