Hikvision DS-3E1552P-SI is a smart managed 48-port Gigabit PoE switch with a 470W PoE power budget, 2 additional Gigabit RJ45 uplink ports and 2 Gigabit SFP fibre uplink ports, supporting IEEE 802.3af/at PoE standards, long-range PoE up to 300 metres, PoE Watchdog, VLAN, QoS, SNMP, STP/RSTP and Hik-Partner Pro remote management. Designed for surveillance system deployments, it is suitable for large-scale IP camera installations requiring centralised, remotely managed PoE switching.

Hikvision DS-3E1552P-SI Smart Managed 48-Port Gigabit PoE Switch — 470W, 300m Long Range, SFP Uplinks

The Hikvision DS-3E1552P-SI is a smart managed Layer 2 Gigabit PoE network switch from Hikvision's Smart Managed series, providing 48 Gigabit PoE ports (IEEE 802.3af/at), 2 additional Gigabit RJ45 uplink ports and 2 Gigabit SFP fibre uplink ports in a standard 1U rack-mount chassis. With a total PoE power budget of 470W and support for long-range PoE transmission up to 300 metres, it is designed for IP camera and surveillance system deployments requiring high-density PoE switching with professional network management capability.

The switch integrates with Hikvision's software platforms — including Hik-Partner Pro, Hik-Central Pro and web browser management — allowing installers to deploy, monitor and manage the switch and connected PoE devices remotely, view network topology, monitor health and receive real-time device alarms without on-site visits.

48-Port Gigabit PoE with 470W Power Budget

All 48 RJ45 ports (ports 1–48) deliver Gigabit data and PoE power simultaneously, compliant with IEEE 802.3af (up to 15.4W per port) and IEEE 802.3at PoE+ (up to 30W per port) standards. The total PoE power budget of 470W is shared across all 48 PoE ports, allowing a mix of standard PoE and PoE+ devices to be powered and connected from a single switch. Maximum per-port PoE power output is 30W.

Long-Range PoE — Up to 300 Metres

Long-range mode extends PoE and data transmission to up to 300 metres on a single CAT5e or CAT6 cable on ports 1–48, significantly beyond the standard 100-metre Ethernet limit. This reduces the need for additional switches, extenders or media converters in larger installations such as car parks, campus sites, warehouses and perimeter locations where cameras are mounted at distance from the network cabinet.

Long range performance may vary depending on camera model and cable condition. This mode can be enabled per port via the web interface or Hik-Partner Pro.

PoE Watchdog — Automatic Camera Recovery

The PoE Watchdog function continuously monitors connected PoE devices on ports 1–48. If a connected device stops responding — as can happen when an IP camera locks up or crashes — the switch automatically detects the failure and restarts power to that port, rebooting the camera without requiring manual intervention. This helps maintain continuous recording without on-site visits, particularly useful in unattended or remote camera locations.

4 Uplink Ports — RJ45 and SFP Fibre

The switch provides 2 additional Gigabit RJ45 uplink ports and 2 Gigabit SFP fibre uplink ports (ports 49–52) for connection to upstream switches, NVRs or network infrastructure. SFP ports support standard Gigabit SFP modules for single-mode or multi-mode fibre connections, extending uplink reach to remote network rooms or between buildings. Link aggregation (static, up to 8 groups) is supported across uplink ports for bandwidth expansion and redundancy.

VLAN — Network Segmentation

The switch supports 802.1Q VLAN with VLAN IDs configurable from 1 to 4094 and a maximum of 4094 VLANs, in Trunk and Access port modes. VLAN segmentation allows camera traffic to be isolated from office data networks, improving security and reducing broadcast traffic on large installations. Port isolation mode is also supported on ports 1–52, preventing direct communication between ports in the same isolation group while maintaining uplink connectivity.

QoS — Traffic Prioritisation

Port-based QoS priority configuration is supported with SP (Strict Priority) and WRR (Weighted Round Robin) scheduling modes, allowing video streaming traffic from cameras to be prioritised over lower-priority data on the same network infrastructure. This helps ensure smooth, uninterrupted video transmission even when the network is under load.

STP/RSTP and Loop Prevention

The switch supports 802.1D STP, 802.1w RSTP and G.8032 ERPS (Ethernet Ring Protection Switching) for loop prevention in complex network topologies. Storm control is included to protect against broadcast, multicast and unknown unicast traffic storms that can degrade network performance.

SNMP and Port Mirroring

SNMP is supported for integration with third-party network management platforms. Port mirroring is included for network fault diagnosis and traffic analysis. LLDP (802.1ab) is supported for peer device discovery and network topology mapping. Cable detection allows identification of open circuits, short circuits and cable length measurement without physical access to the cable run.

Hik-Partner Pro and Hik-Central Pro Integration

The switch supports one-click activation and full remote management via Hik-Partner Pro, allowing installers to manage switches in the field without on-site access. Functions available via Hik-Partner Pro include port rate display, port bandwidth utilisation monitoring, PoE power usage monitoring, topology display, alarm status viewing, port and device restart, long-range mode activation and remote firmware upgrade. Hik-Central Pro integration is also supported for unified surveillance platform management.

Web Management and Super IP

The switch is managed via web browser with DHCP client enabled by default for dynamic IP assignment. A fixed Super IP address (10.180.190.200) provides direct access for initial configuration without requiring prior DHCP setup. DHCP snooping is not required — the switch is accessible immediately after power-up.

FREQUENTLY ASKED QUESTIONS (FAQs)

What is the Hikvision DS-3E1552P-SI used for?

It is a smart managed 48-port Gigabit PoE switch designed for IP camera and surveillance system installations. It powers and connects up to 48 PoE cameras from a single switch with a 470W power budget, supports long-range PoE up to 300m and provides VLAN, QoS, PoE Watchdog and remote management via Hik-Partner Pro.

How many cameras can it power simultaneously?

Up to 48 cameras across ports 1–48, subject to the total 470W PoE power budget. For example, 48 cameras drawing 9.5W each (standard PoE) would use approximately 456W total — within budget. Cameras drawing 25–30W each (PoE+) would require fewer simultaneous connections or careful power allocation. Always confirm total power draw against the 470W budget for your specific camera mix.

What is long-range PoE and how does it work?

Long-range mode extends PoE and data transmission from the standard 100m limit to up to 300 metres on a single cable. It is enabled per port via the web interface or Hik-Partner Pro. Performance may vary depending on cable quality and camera model. This eliminates the need for PoE extenders or additional switches at distance in large sites.

What is PoE Watchdog?

PoE Watchdog monitors connected PoE devices and automatically detects when a device stops responding. When a failure is detected, the switch automatically power-cycles the affected port, rebooting the camera or device without requiring manual intervention. This is particularly valuable for cameras in remote or unattended locations.

Does it support fibre uplinks?

Yes. Two Gigabit SFP fibre uplink ports (ports 51–52) support standard Gigabit SFP modules for single-mode or multi-mode fibre connections to upstream switches or NVRs in remote network rooms or other buildings.

Can it be managed remotely?

Yes. Full remote management is available via Hik-Partner Pro, allowing installers to monitor port status, PoE power usage, network topology and device alarms, restart ports and devices, enable long-range mode and upgrade firmware — all without visiting the site. Hik-Central Pro integration is also supported.

Does it support VLAN?

Yes. 802.1Q VLAN is supported with up to 4094 VLANs in Trunk and Access port modes, allowing camera traffic to be isolated from office or guest networks. Port isolation mode is also available to prevent direct camera-to-camera communication.

What is the Super IP and how is it used?

The Super IP (10.180.190.200) is a fixed management IP address built into the switch, accessible directly without DHCP configuration. Connect a laptop directly to the switch and browse to this address to access the web management interface for initial setup.
