Chapter 4. Continuous availability and manageability 183
With two CEC enclosures and more, there are two redundant FSP, one in each of the first
CECs. While one is active, the second one is in standby mode. In case of a failure, there will
be a automatic takeover.
The service processor uses two Ethernet 10/100Mbps ports. Note the following information:
򐂰 Both Ethernet ports are only visible to the service processor and can be used to attach the
server to an HMC or to access the ASMI. The ASMI options can be accessed through an
HTTP server that is integrated into the service processor operating environment.
򐂰 Both Ethernet ports support only auto-negotiation. Customer selectable media speed and
duplex settings are not available.
򐂰 Both Ethernet ports have a default IP address, as follows:
– Service processor Eth0 or HMC1 port is configured as 169.254.2.147.
– Service processor Eth1 or HMC2 port is configured as 169.254.3.147.
򐂰 When a redundant service processor is present, the default IP addresses are:
– Service processor Eth0 or HMC1 port is configured as 169.254.2.146.
– Service processor Eth1 or HMC2 port is configured as 169.254.3.146.
The functions available through service processor include:
򐂰 Call Home
򐂰 Advanced System Management Interface (ASMI)
򐂰 Error Information (error code, PN, Location Codes) menu
򐂰 View of guarded components
򐂰 Limited repair procedures
򐂰 Generate dump
򐂰 LED Management menu
򐂰 Remote view of ASMI menus
򐂰 Firmware update through USB key
Advanced System Management Interface (ASMI)
ASMI is the interface to the service processor that enables you to manage the operation of
the server, such as auto-power restart, and to view information about the server, such as the
error log and vital product data. Various repair procedures require connection to the ASMI.
The ASMI is accessible through the management console. It is also accessible by using a
web browser on a system that is connected directly to the service processor (in this case,
either a standard Ethernet cable or a crossed cable) or through an Ethernet network. ASMI
can also be accessed from an ASCII terminal, but this is only available while the system is in
the platform powered-off mode.
Use the ASMI to change the service processor IP addresses or to apply certain security
policies and prevent access from undesired IP addresses or ranges.
Note: The service processor enables a system that does not boot to be analyzed. The
error log analysis can be performed from either the ASMI or the management console.
