Allied Telesis AT-x530L-18GHXm-10 vs Allied Telesis GS970M/18PS-R-10: Specification Comparison
Both the AT-x530L-18GHXm-10 and the GS970M/18PS-R-10 are Allied Telesis 1U rack-mount switches with 16 PoE-enabled ports and 2 uplink ports, targeting physical-security and IoT deployments where powered endpoints—cameras, access control readers, and wireless APs—must share a single switching tier. The key differentiators are PoE standard (PoE++ at up to 90 W per port versus PoE+ at up to 30 W per port), copper port speed (multi-gigabit up to 5 Gbps versus gigabit), and aggregate switching capacity, making these a genuine cross-shop for installers sizing a PoE edge layer.

Which switch delivers more PoE power and higher per-port bandwidth for demanding endpoints?
The AT-x530L-18GHXm-10 provides a 720 W total PoE budget across its 16 multi-gigabit copper ports, with per-port flexibility of 7.5 W, 15.4 W, 30 W, 60 W (12 ports), or 90 W (8 ports) — all conforming to IEEE 802.3bt PoE++. This makes it suitable for pan-tilt-zoom cameras with integrated heaters, multi-radio Wi-Fi 6E access points, and thin-client terminals that draw above the 30 W PoE+ ceiling.
The GS970M/18PS-R-10 provides a 247 W total PoE budget across 16 standard 10/100/1000T copper ports, supporting up to 15 W per port across all 16 ports simultaneously, or up to 30 W per port on 8 ports under IEEE 802.3at PoE+. It does not support 60 W or 90 W per-port delivery. For fixed IP cameras, standard PoE access points, and VoIP phones that stay within the 30 W envelope, the 247 W budget is adequate; for high-wattage endpoints it is a hard ceiling.
Port speed is a further differentiator: the x530L's 16 access ports run at 100 M / 1 / 2.5 / 5 Gbps, accommodating multi-gigabit Wi-Fi 6/6E backhaul or high-bitrate camera streams without uplink contention. The GS970M/18PS-R-10's 16 access ports are capped at 1 Gbps. Latency at 10 Gbps on the x530L is specified at 2.56 µs; at 5 Gbps, 5.23 µs. Equivalent per-speed latency figures are not published for the GS970M/18PS-R-10.
How do switching fabric, forwarding rate, and uplink options compare for traffic aggregation?
The AT-x530L-18GHXm-10 has a 200 Gbps switching fabric and a 148.8 Mpps forwarding rate. Its two uplink ports are 1/10 Gbps SFP+, allowing 10GbE fibre or DAC connections to an aggregation layer. Additionally, the x530L carries two stacking ports, enabling daisy-chain clustering; Allied Telesis describes this as supporting unified management across stacked units. The combination of 10G uplinks and stacking is directly relevant in larger deployments where multiple edge switches must be managed as a single logical unit.
The GS970M/18PS-R-10 has a 36 Gbps switching fabric and a 26.8 Mpps forwarding rate. Its two uplink ports are 100/1000X SFP — 1 Gbps fibre, not 10 Gbps. No stacking capability is listed in the provided specifications. For a single-closet installation with moderate camera counts, the 36 Gbps fabric is non-blocking at gigabit access speeds, but the 1 Gbps uplink ceiling becomes a bottleneck if aggregate access traffic approaches line rate or if the switch must trunk to a 10G core.
In absolute terms the x530L's fabric is 5.6× larger (200 Gbps vs 36 Gbps) and its forwarding rate is 5.6× higher (148.8 Mpps vs 26.8 Mpps), reflecting both the higher per-port speeds and the broader uplink capacity.
What are the power, thermal, acoustic, and physical footprint trade-offs between these two switches?
The AT-x530L-18GHXm-10 draws up to 970 W maximum (inclusive of the 720 W PoE budget), dissipates up to 3,317 BTU/hr, and produces up to 42 dBA of acoustic noise. Its chassis measures 441 × 256 × 44 mm and weighs 4.3 kg unpackaged. The 970 W draw demands a circuit and UPS provisioned well above the 720 W PoE allocation; rack-level thermal planning must account for 3,317 BTU/hr.
The GS970M/18PS-R-10 draws up to 330 W maximum (inclusive of the 247 W PoE budget), dissipates up to 169 BTU/hr, and produces up to 34 dBA of acoustic noise. Its chassis is more compact at 341 × 231 × 44 mm and weighs 4.35 kg. The 8 dBA lower noise specification and the 169 BTU/hr versus 3,317 BTU/hr thermal output represent meaningful differences for installations in noise-sensitive environments or closets with limited cooling.
Both switches occupy a single 1U rack slot, so rack-unit footprint is equivalent. The GS970M/18PS-R-10 is 100 mm shorter in depth (231 mm vs 256 mm), which may benefit shallow-depth cabinets. Packaged dimensions are provided for both units; unpackaged weight is within 0.05 kg of each other despite the significant capability gap, indicating a similar chassis construction approach.
Which should you choose: the AT-x530L-18GHXm-10 or the GS970M/18PS-R-10?
Our take: The AT-x530L-18GHXm-10 is the stronger choice when the deployment includes high-wattage endpoints (PTZ cameras with heaters, Wi-Fi 6E APs, or multi-radio devices exceeding 30 W), requires multi-gigabit access speeds above 1 Gbps, or must scale through stacking and 10G uplinks. Concretely: its 720 W PoE budget is 2.9× the GS970M/18PS-R-10's 247 W; its switching fabric is 5.6× larger (200 Gbps vs 36 Gbps); and its SFP+ uplinks run at 10 Gbps versus the GS970M/18PS-R-10's 1 Gbps SFP. The GS970M/18PS-R-10 is the more appropriate platform for standard gigabit PoE+ deployments — fixed dome cameras, standard APs, VoIP handsets — where total PoE draw stays within 247 W, all endpoints are 30 W or below, and the installation environment prioritises lower acoustic noise (34 dBA vs 42 dBA) and reduced thermal load (169 BTU/hr vs 3,317 BTU/hr).

Frequently Asked Questions
Which should you choose: the AT-x530L-18GHXm-10 or the GS970M/18PS-R-10?
The AT-x530L-18GHXm-10 is the stronger choice when the deployment includes high-wattage endpoints (PTZ cameras with heaters, Wi-Fi 6E APs, or multi-radio devices exceeding 30 W), requires multi-gigabit access speeds above 1 Gbps, or must scale through stacking and 10G uplinks. Concretely: its 720 W PoE budget is 2.9× the GS970M/18PS-R-10's 247 W; its switching fabric is 5.6× larger (200 Gbps vs 36 Gbps); and its SFP+ uplinks run at 10 Gbps versus the GS970M/18PS-R-10's 1 Gbps SFP. The GS970M/18PS-R-10 is the more appropriate platform for standard gigabit PoE+ deployments — fixed dome cameras, standard APs, VoIP handsets — where total PoE draw stays within 247 W, all endpoints are 30 W or below, and the installation environment prioritises lower acoustic noise (34 dBA vs 42 dBA) and reduced thermal load (169 BTU/hr vs 3,317 BTU/hr).
Is the AT-x530L-18GHXm-10 or GS970M/18PS-R-10 better for a deployment with high-power PTZ cameras or Wi-Fi 6E access points?
The AT-x530L-18GHXm-10 is better suited. It supports up to 90 W per port (on 8 ports) and 60 W per port (on 12 ports) under IEEE 802.3bt PoE++, with a 720 W total budget. The GS970M/18PS-R-10 is capped at 30 W per port (on 8 ports) under IEEE 802.3at PoE+, with a 247 W total budget. Devices requiring more than 30 W cannot be powered by the GS970M/18PS-R-10.
Can either switch stack with other units for unified management across a larger site?
Stacking ports are specified only for the AT-x530L-18GHXm-10, which includes 2 stacking ports for daisy-chain clustering. The provided specifications for the GS970M/18PS-R-10 do not list stacking capability. Buyers requiring multi-switch unified management should verify GS970M/18PS-R-10 stacking support directly with Allied Telesis documentation before selection.
Which switch is more suitable for a wiring closet where heat and noise are a concern?
The GS970M/18PS-R-10 produces significantly less heat and noise: 169 BTU/hr and 34 dBA versus the AT-x530L-18GHXm-10's 3,317 BTU/hr and 42 dBA. For installations in noise-sensitive areas or closets with limited cooling capacity, the GS970M/18PS-R-10 presents a substantially lower thermal and acoustic burden, provided its 247 W PoE budget and 1 Gbps access port speeds are sufficient for the endpoint mix.
