Adding RAID Controller Modules with More Than One Ethernet Port
When your has more than one port, consider these cabling guidelines:
Use one Ethernet port from each RAID controller module to connect to your storage array.
Use the other Ethernet port from each RAID controller module to connect to an externally
accessible network, which allows the Technical Support representative to access the storage
array. This configuration permits the Technical Support representative to assist you with
troubleshooting and upgrading your storage array without having access to your data.
When configuring the Ethernet ports, make sure that the port configured for the Technical
Support representative is on a separate from the storage array port. Configuring both ports with the same subnet causes a
“Hardware Ethernet Conflict” error.
When cabling your RAID controller modules, be consistent about selecting which port will
connect to which network. For example, the Ethernet ports are labeled 1 and 2 on each RAID
controller module. Choose port 1 from RAID controller module 0 and port 1 from RAID
controller module 1 to use to manage your storage array. Choose port 2 from RAID controller
module 0 and port 2 from RAID controller module 1 to provide external access for the
Technical Support representative.
