Huawei storage enclosure components and PDUs (137 P/Ns)

Four unrelated things in one group

This group holds 137 part numbers and it is the most heterogeneous on the site. It contains chassis mechanics, backplanes, cabinet power distribution and cosmetic nameplate kits. They share a catalogue grouping, not a function.

The practical consequence is that you cannot search this group by model. A PDU is qualified by electrical rating; a backplane by enclosure generation; a nameplate kit by the exact enclosure variant it dresses. Three different matching rules in one list.

PDUs are specified in kVA, not in ports

10 rows are power distribution units or distribution boxes. A PDU is chosen by electrical capacity and by input topology, and the count of outlets follows from those two. The ratings present here are 7 kVA 3, 7.6 kVA 2, 22 kVA 2.

• Single-phase and three-phase inputs are not interchangeable, and the difference is in the part number.
• Input cord length is part of the part: 3 m is common and is stated in the description.
• Basic and metered PDUs look the same in a rack and behave differently in a capacity plan.
• DC distribution boxes exist alongside AC ones and are a separate product line.

Nameplate kits explain why this group looks over-counted

17 of the 137 rows are nameplate, mask or label packages. They are genuine spare parts — a chassis returned to a customer with the wrong branding on the front is a rejected chassis — but they carry no electrical or mechanical function. If you are scanning this list for something to fix a fault, these are not it.

• A nameplate kit is matched to the exact enclosure variant: bay count, drive type and generation.
• Mask packages cover unused bays; the count of masks follows the bay count.
• Label packages are matched to the module they label, not to the enclosure.

Backplanes and midplanes are generation-bound

5 rows are backplanes or midplanes. These are the boards every drive and every module plugs into, and they are the most generation-bound parts in the whole spare-parts catalogue. A backplane from the wrong generation will physically accept the drives and will not carry the lanes they need.

• Match the enclosure model and the generation, not the bay count.
• SAS and NVMe backplanes are different products even when the bay count matches.
• A backplane swap is a full enclosure service action: plan the outage, not just the part.

Rails and mounting hardware

Rails, brackets and mounting ears appear here because they are orderable spares and because they are routinely lost between sites. Cabinet depth is the variable: a rail set for a 1000 mm cabinet does not fit a 1200 mm cabinet, and the part number does not say so unless you read the description.

Full part-number list, 137 P/Ns

Descriptions are the official catalogue text. Where a row is a kit rather than a single component, the description says what is in the kit.

Before you order from this group

• Decide which of the four component types you need; they are matched by different rules.
• For a PDU, confirm phase, voltage and kVA before anything else.
• For a backplane, confirm enclosure model and generation.
• For a nameplate kit, confirm the exact enclosure variant and bay count.
• For rails, confirm cabinet depth.

Frequently asked questions

Is a PDU interchangeable between cabinets?

Only if phase, voltage and kVA match, and the input cord reaches. The outlet count alone is not the specification.

Can I fit a SAS backplane where an NVMe backplane was?

No. They are different products with different lane routing, even when the bay count is identical.

Why are nameplate kits sold as spare parts?

Because a chassis with the wrong branding is rejected at handover. They are genuine spares with no electrical function.

Do rails fit any cabinet?

No. Rail sets are matched to cabinet depth. The depth is in the description, not in the part number.

How do I identify a backplane generation?

From the enclosure model and the generation code in the description. Send us the enclosure model and we confirm the part.
