HPE Aruba Networking CX 8325H 4-Post Rack Mount Shelf Kit
HPE S2T43ACX 8325H only1 or 2 half-width switchesPair with J9583B
The HPE Aruba Networking CX 8325H 4-post Rack Mount Shelf Kit (S2T43A) is the tray that mounts one or two half-width Aruba CX 8325H switches side by side in a four-post 19-inch rack or cabinet. It is for data-centre and campus-core teams deploying the 8325H, which is a half-width switch and ships without rack-mount brackets.
HPE's 8325H installation guide specifies that this tray must be paired with the Aruba X414 1U Universal 4-post Rack Mount Kit (J9583B): the tray holds the switches, the J9583B provides the four-post rail mounting. The switches slide into the tray and lock with a latch, and power cord retention clips keep the power cables in place.
Before you order: This tray must be ordered together with the Aruba X414 1U Universal 4-post Rack Mount Kit (J9583B). On its own it cannot be fixed into a four-post rack. For two-post racks HPE offers a different kit, S2T44A.
What's in the Box
- Rack mount tray for one or two half-width CX 8325H switches
- The four-post rail kit is not included — order Aruba X414 J9583B with it
- The 8325H switches are not included
What It Means in Practice
- Two half-width 8325H switches fit side by side in one tray, so a redundant pair shares the same rack position.
- If only one switch is installed, HPE offers a blank panel (S5D79A) to fill the empty tray slot.
- The switch measures 8.27 × 22.70 × 1.69 in (W × D × H), so plan rack depth for a deep 1U device and its cabling.
- Check airflow direction: 8325H models come in front-to-back and back-to-front versions, and HPE recommends positioning them to avoid recirculating hot air.
What Will Not Work
- Any switch other than the Aruba CX 8325H series.
- Mounting in a four-post rack without the J9583B rail kit.
- Two-post racks — use the HPE Aruba Networking 8325H 2-post Rack Mount Kit (S2T44A) instead.
- Full-width switches — the tray is designed for half-width 8325H units.

Frequently Asked Questions
Does the 8325H come with rack ears?
No. HPE states the 8325H switches ship without brackets, so a tray kit is needed to rack-mount them.
Is J9583B really required?
Yes. HPE's installation guide says S2T43A must be paired with the Aruba X414 1U Universal 4-post Rack Mount Kit (J9583B).
Which 8325H models does it fit?
All 8325H variants listed by HPE: S4B20A, S4B21A, S4B22A, S4B23A, S2T42A, S2T46A, S2T47A and S2T48A, in both airflow directions.
Singular Expert Insight · Buyer's Guide
The 8325H is half-width, so racking it is always a two-part order: this tray plus the J9583B four-post rails, or the S2T44A kit for two-post racks. Ordering both parts together avoids a switch sitting on a shelf waiting for hardware. See our
network switches for the switches themselves.
✓ Buy it if you are installing one or two Aruba CX 8325H switches in a four-post rack and are also ordering J9583B.
✕ Skip it if your rack is two-post (use S2T44A) or your switch is not an 8325H.
→ Also consider Aruba X414 J9583B (required), and S5D79A blank panel if you install a single switch.
