HPE Aruba Networking CX 6000 R8N88A 24-Port Data Switch with 4x 1G SFP
- Managed, Rack-mountable, 24 x 1G ports, 4 x 1G SFP Uplinks, No PoE (Data Only), Layer 2
Overview
HPE positions the CX 6000 Switch Series as a modern family of entry-level access switches for branch offices, midsize businesses and small enterprises, built on the HPE Aruba Networking ASIC architecture and the AOS-CX operating system used across the CX portfolio. The R8N88A is the 24-port data-only model of the original CX 6000 A line: 24 Gigabit access ports and four fixed 1G SFP uplinks on a single fixed power supply, in a 20.12 cm-deep 1U chassis. Its axis within the CX family is simplicity: Gigabit uplinks, static routing and standalone operation, where the CX 6100 adds 1G/10G SFP+ uplinks and VSF stacking (AOS-CX 10.16.1006 or later). The closely matched R8N87A shares the 24-port, 4x 1G SFP layout and adds Class 4 Power over Ethernet.
Technical Details
The HPE Aruba Networking CX 6000 R8N88A is a Layer 2+ managed 1U rackmount switch with 24 Gigabit (10/100/1000BASE-T) access ports and four fixed 1G SFP uplinks, running AOS-CX. Switching capacity is 56 Gbps and forwarding rate is 41.6 Mpps. It carries no Power over Ethernet, so all 24 access ports are data-only. Routing is static IPv4 and IPv6. Switch software is embedded, with no subscription required to enable it. It connects desktops, printers and wired IoT devices in smaller branch and campus wiring closets.
Best For
The R8N88A suits smaller branch and campus wiring closets that connect up to 24 wired endpoints such as desktops, printers and wired IoT devices that do not need power from the switch, with Gigabit fiber or copper uplinks to the distribution layer.
Not suitable if:
- you need more than 24 access ports, since this model has 24
- you need to power access points, phones or cameras, since this model has no Power over Ethernet
- you need 10G uplinks, since the uplinks on this model are 1G
- you need switch stacking, because this model's documents list no stacking technology
- you need dynamic routing such as OSPF or BGP, since routing is limited to static IPv4 and IPv6 routes
- you need multigigabit access ports, since the access ports are 10/100/1000BASE-T

FAQ
Does the HPE Aruba Networking CX 6000 R8N88A support PoE?
No. The HPE Aruba Networking CX 6000 R8N88A is a data-only switch: its 24 Gigabit access ports carry no Power over Ethernet, so it cannot power wireless access points, IP phones or security cameras. If the switch must power those devices, the R8N87A is the 24-port CX 6000 model with IEEE 802.3at Class 4 Power over Ethernet and a 370 W budget, with the same four 1G SFP uplinks.
What transceivers do the R8N88A uplinks use?
The R8N88A has four fixed 1G SFP uplink ports. They are 1-Gigabit SFP slots, so 10G SFP+ optics are not supported on this model. HPE listed 1G SFP SX, 1G SFP LX and 1G SFP RJ45 transceivers for the CX 6000. Unsupported Transceiver Mode can enable other 1G transceivers, but HPE does not support the transceiver or cable when that mode is used. Transceivers are sold separately.
Can the R8N88A be stacked?
No. HPE's CX 6000 QuickSpecs and data sheet list no stacking technology, so the R8N88A is managed as an individual switch. For link resilience HPE lists IEEE 802.3ad LACP with up to 8 LAGs of up to 8 links each, IEEE 802.1s MSTP with RSTP, UDLD and SmartLink active/standby uplink pairs. HPE listed Switch Multi-Edit for pushing configuration to many switches at once. If stacking is a requirement, look at a series whose documents list VSF, such as the CX 6100.
What is the difference between the R8N88A and the R8N87A?
Both are 24-port CX 6000 A-line switches with four 1G SFP uplinks, 56 Gbps switching capacity, 41.6 Mpps forwarding and 4 GB DDR3 / 16 GB eMMC. The R8N87A adds IEEE 802.3at Class 4 Power over Ethernet with a 370 W budget; the R8N88A has none. The R8N88A is also shallower and lighter: 20.12 cm and 5.78 lb versus 26.82 cm and 9.24 lb. Choose the R8N88A when no attached device needs power from the switch.
How does the R8N88A differ from the R8N88B?
The R8N88B is the B version of the same 24-port data-only, 4x 1G SFP configuration, and HPE publishes the same 56 Gbps and 41.6 Mpps for both. Differences documented by HPE include memory (4 GB DDR3 and 16 GB eMMC on the R8N88A versus 2 GB DDR3 and 8 GB eMMC on the R8N88B), weight (5.78 lb versus 5.05 lb) and Trusted Platform Module 2.0, which HPE's QuickSpecs lists for CX 6000 rev-B models only.
How is the R8N88A managed?
The R8N88A is a fully managed switch. HPE lists a web GUI, an industry-standard CLI, REST APIs and Zero Touch Provisioning. For configuring many switches at once HPE listed HPE Aruba Networking Switch Multi-Edit, which required its own separate software license. The switch software itself is embedded, with no subscription required to enable it. Routing is limited to static IPv4 and IPv6 routes; the CX 6000 documents list no dynamic routing protocol.
Is the R8N88A end of sale?
Yes. HPE announced the end of sale of the CX 6000 A switches on November 30, 2025, in its "HPE Aruba Networking 6000 A Switch End of Sale Announcement", with an End of Sale date of March 31, 2026. The notice lists the End of Support Life date as to be determined. HPE names the R8N88B (HPE Aruba Networking CX 6000 24G 4SFP) as the replacement for the R8N88A.
What condition is the R8N88A sold in, and what warranty applies?
The R8N88A is sold new and factory-sealed. It is covered by the Network Devices Inc. 1-year warranty and a 30-day return policy.
