NOTE:

Limit the amount of slack between the enclosure and the CMA. Any excess cable should be routed outside of the

CMA and bundled neatly when cabling is complete.

4. Turn on the host system.

Cabling the enclosure

You can cable the storage enclosure to a single host system and to additional storage enclosures in the following configurations:

● Redundant configuration using a four-port adapter.

○ HBA 355e is supported on PowerEdge 14G, 15G, and 16G servers.

○ PERC H965e is supported only on PowerEdge 16G servers.

● Redundant configuration using a two-port PERC H840 (PowerEdge 14G and 15G servers).

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

● Always use SAS4 cables for connections between enclosures. See your system deployment information for specific details

about connecting enclosures.

○ When an enclosure 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 an enclosure 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 cabled to the server for the enclosure to

function properly.

● These enclosures does 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.

Redundant configuration using an HBA355e adapter

This configuration supports two enclosures in two separate chains. The HBA 355e is supported on PowerEdge 14G, 15G, and

16G servers.

Redundant configuration using a PERC H965e

This configuration supports up to four enclosures in two separate chains. The PERC H965e is supported only on PowerEdge 16G

servers.
