Chapter 7. Host port protocol conversion
7.1. Requirements for changing the host port protocol
Before converting the host protocol for a DE2000H or DE4000H array, review
the requirements.
7.1.1. Host ports you can change
The following figure shows the back of a DE2000H or DE4000H controller that has two SFP+
(optical) baseboard host ports (1) and four SFP+ (optical) HIC ports (2).

A two-port HIC is also available.
The following figure shows the back of a DE2000H or DE4000H controller (without two SFP+
(optical) baseboard host ports) with four HIC ports (1).

For the system without base ports, 2x HICs are required to make the system work
normally. Systems without HICs installed are not allowed to be powered on.
The DE2000H or DE4000H controller or controllers in your storage array might have different types
of baseboard host ports and different types of HIC ports. The table shows which host ports can be
changed with a feature pack.
