HPE Aruba Networking CX 6405 v2 — 5-slot modular switch bundle
7U modular chassis5 line module slotsMgmt module includedAOS-CX
The HPE Aruba Networking CX 6405 v2 Switch (R0X26C) is a 7U modular switch bundle for campus core and aggregation, built around the 6405 v2 chassis with one management module and both fan trays already installed.
The 6400 series lets you build the switch you need from line modules — access, aggregation and high-speed uplink cards — in five line slots, with a second management module slot for redundancy and four power-supply bays. It runs the AOS-CX operating system shared across the Aruba CX range. Because the bundle ships without power supplies and without line modules, it is the starting point for a configured system rather than a ready-to-run switch.
Before you order: Power supplies and line modules are NOT included. To operate you need at least one supported PSU (R0X35A or R0X36A) and at least one 6400-series line module. Send us your port requirements and we will configure the full bill of materials.
What's in the Box
- Aruba 6405 v2 chassis (R0X24C)
- 1x Aruba 6400 Management Module (R0X31A) — second slot open
- 2x Aruba 6400 Fan Trays (R0X32A)
- 2-post rack mounting kit
What It Means in Practice
- Choose line modules for your mix of access and uplink ports — all five slots are open.
- Add 1 to 4 power supplies; more PSUs give redundancy.
- A second management module (sold separately) adds control-plane redundancy.
- For 4-post racks order the R0X37A 4-post rack kit.
What Will Not Work
- Does not power on or pass traffic as delivered — PSU and line modules are required.
- No 4-post rack kit in the box (R0X37A sold separately).
- Not compatible with non-6400 line cards.
- Not a fixed-port access switch — for small networks a stackable CX switch is simpler.
