Connect SAS cables to the host system and then connect the power cables to the enclosure.

You can cable the storage enclosure using either a four-port HBA or a two-port PERC:

● A four-port SAS HBA supports up to eight MD2412 enclosures or four MD2424 enclosures.

● A two-port PERC adapter supports up to four 2U enclosures.

Make sure that you follow these instructions when you are connecting enclosures in a chain configuration:

● Always use SAS4 cables for connections between enclosures. Refer to your system deployment information for specific

details about connecting enclosures.

○ When a SAS4 cable is connected to a SAS4 HBA, the SAS LEDs on the EMMs turn green to indicate that the port link is

working at the SAS4 speed.

○ When a SAS4 cable is connected to a SAS3 HBA, the SAS LEDs on the EMMs turn amber to indicate that the port link is

working, but at a degraded speed.

● This enclosure only supports redundant configurations. Both EMMs must be connected to the server for the enclosure to

function properly.

● These enclosures do not support asymmetrical cabling. All cables must run from top to bottom or bottom to top in a stack.

● Do not connect different enclosure models in a chain configuration.
