5: Cabling
Out-of-band management requires that Ethernet or serial connections are cabled to each
controller. The controllers are managed directly from a management station through the
connections on each controller.
In-band management requires that only the Fibre Channel host interface is present and
functional. The controllers are managed from a management station through a host
using the I/O connections between the host and the controllers. See Figure 5-12 on
page 80 for an example cabling diagram.
Note: For more information on storage management, see the SGI InfiniteStorage TPSSM
Software Concepts Guide (007-4749-00x) and SGI InfiniteStorage TPSSM Administration
Guide (007-4748-00x).
To connect Ethernet or serial (RS-232) interface cables to the controller enclosure for
direct management of the storage array, follow the steps in this section. Optionally, you
can use the Ethernet or serial connectors for diagnostic procedures.
Warning: Electrostatic discharge can damage sensitive components. Use
appropriate antistatic precautions before handling any components.
See the following steps and illustrations for examples of out-of-band and in-band
management connectivity.
