Ensure that all firmware is up-to-date before attaching the blades together. For the minimum

firmware requirements, see 8.2.3, "Required firmware of each blade and the AMM" on

For configuring software when using a 2-node for creating the partition in a scalable complex,

using Flexnode to toggle between a single blade and a 2-node, and deleting the partition, see

8.6, "Creating an HX5 scalable complex" on page 402.

Important: When a blade is attached, it does not automatically become a 2-node

single-image system. You must create the 2-node single-image system by using the

scalable complex in the Advanced Management Module (AMM) in the chassis. See 8.6,

"Creating an HX5 scalable complex" on page 402 for more information.

5.8.3 HX5 with MAX5

In the HX5 and MAX5 configuration, the HX5 and MAX5 units connect through a 1-node

MAX5 scalability card, which provides QPI scaling. See Figure 5-10 on page 191.
