Step 8 - Connecting the Ethernet cables
Use this step if you are using out-of-band management for your storage array. If you use in-band
management, you can ignore this step and continue with

Key terms
In-band management
A method to manage a storage array in which a storage management station sends commands to the
storage array through the host input/output (I/O) connection to the controller. The SMagent must be
installed for this method to work correctly.
Out-of-band management
A method to manage a storage array in which a storage management station sends commands to the
storage array through the Ethernet connections to the controller. This is the recommended
management method.
Things to know - Connecting Ethernet cables
This topic describes Ethernet management connections. It does not describe the Ethernet iSCSI
connections that might be used through a host interface card connection.
Attention: Risk of security breach – Connect the Ethernet ports on the controller-drive tray to a
private network segment behind a firewall. If the Ethernet connection is not protected by a firewall,
your storage array might be at risk of being accessed from outside of your network.
The figure shows a controller with Ethernet port 1 and Ethernet port 2.
Note: Ethernet port 2 on each controller is reserved for access by technical support.
Because the controllers support the Auto-MDIX feature, you do not need an Ethernet crossover
cable.
