48 managed PoE+ access ports with a shared 370 W budget
48 × Gigabit PoE+370 W standard PoE4 × 10G SFP+Physical stacking
The D-Link DGS-1530-52P/E combines 48 Gigabit PoE+ access ports with four 10G SFP+ interfaces in a stackable managed switch. Its standard shared PoE budget is 370 W, with up to 30 W on a single copper port within that total. VLAN, access controls and supported static routing help integrate powered access points, phones and cameras into a planned business network.
Best For: Managed office and campus access networks with many PoE+ endpoints and 10G uplink requirements.
Before you order: Calculate all powered-device requirements against the standard 370 W combined allowance. The optional, separately sold DPS-700 RPS can expand the documented budget to 740 W; that is not the supplied configuration. Forty-eight 30 W loads exceed either budget. Plan compatible optics, stacking port allocation, firmware and rack cooling. Three fans mean it is not fanless.
What's in the Box
- DGS-1530-52P/E switch; rack-mount brackets are confirmed by the European datasheet.
- DPS-700 redundant supply, optical modules, fiber/DAC and stacking cables are separate.
- Confirm any additional regional package accessories before installation.
What It Means in Practice
- Connect up to 48 copper devices at supported 10/100/1000 Mbps speeds and power compatible IEEE 802.3af/at endpoints within 370 W total.
- Use four SFP+ cages for compatible 10G uplinks or supported stacking connections.
- Configure VLANs, LACP, spanning tree, access controls and supported static routing for the actual topology.
- Use manufacturer-supported Fast PoE, Perpetual PoE and powered-device alive functions with suitable firmware and configuration. They do not replace a UPS.
What Will Not Work
- The standard budget is 370 W, not 740 W. Extra DPS-700 hardware is required for expansion.
- Up to 30 W per port does not mean 48 ports can all deliver 30 W at once.
- SFP+ interfaces do not supply PoE and modules are separate.
- Stacking consumes suitable SFP+ interfaces; plan their shared uplink use.
- No fanless operation or included redundant power supply is promised.

Frequently Asked Questions
Is 740 W included as standard?
No. Standard shared output is 370 W. The documented 740 W expansion needs a separate compatible DPS-700 RPS.
Can all 48 ports supply 30 W together?
No. That would require 1440 W, exceeding both the standard and expanded budgets. Calculate actual combined requirements.
Is the DPS-700 included?
No. It is a separately sold compatible redundant supply.
Are optics and stack cables included?
No such included components are established. Choose compatible hardware separately.
Is this silent or fanless?
No. The manufacturer lists three smart fans and 52.7 dBA.
Singular Expert Insight
The key planning number is 370 W shared across 48 ports. Many low-power devices may fit, while a smaller group of higher-power devices can exhaust the budget. Treat the DPS-700 as a separate design choice and plan SFP+ uplink/stack allocation, firmware and cooling at the same time.
Buyer’s Guide
✓ Buy it if You need dense managed Gigabit PoE+ access within 370 W and suitable 10G uplinks.
✕ Skip it if You need 740 W as standard, 48 simultaneous 30 W loads or fanless operation.
→ Also consider Combined PoE demand, optional DPS-700, compatible uplink and stack hardware, firmware and rack cooling.
