Frequently Asked Questions
The switch supports IEEE 802.3af and IEEE 802.3at PoE standards, delivering up to 30W per PoE port with a 60W total PoE budget. Plan connected powered devices to avoid exceeding the aggregate power limit.
Is this answer helpful?
CCTV mode isolates ports 1–8 so they cannot communicate with each other while allowing uplink access to ports 9 and 10. This prevents broadcast storms, improves security, and supports extended PoE reach up to 250 meters for cameras.
Is this answer helpful?
Yes, the switch supports wall mounting using M4 screws. It accepts 100–240V AC at 50/60Hz. Verify voltage before powering on and ground the device for enhanced lightning protection.

PWR (green) shows power status; LNK/ACT (green) indicates link and activity (steady for link, blinking for traffic); PoE (orange) indicates PoE connection or abnormal power conditions when blinking.
Is this answer helpful?
Yes. In CCTV mode the DN-953 supports extended PoE reach up to 250 meters for cameras, enabling installs where AC power is unavailable, though cable quality and environment affect achievable distance.
Is this answer helpful?
Operate between 0–40°C with 10–90% non-condensing humidity. Store between -40–70°C. Ensure proper ventilation, avoid moisture, and do not block vents or place on unstable surfaces.

Product Description
Digitus DN-953 Desktop Gigabit Switch, 10x RJ-45, 60W PoE+ Manual
The Digitus DN-953 is a compact desktop Gigabit switch designed for small office, retail, and surveillance deployments. Featuring ten 10/100/1000 Mbps RJ-45 ports with PoE on ports 1–8 and a total PoE budget of 60W, the DN-953 supplies up to 30W per port (IEEE 802.3af/at compatible). Its small footprint (168 x 93 x 32 mm) and robust metal housing make it suitable for both desktop and wall-mounted installations. The switch accepts 100–240V AC input and includes surge protection, wide operating temperatures, and energy-saving features via IEEE 802.3az support.
Key product highlights
The DN-953 supports line-rate forwarding with a 20 Gbps switching capacity and a 2Mbit packet buffer, handling jumbo frames up to 9216 bytes and maintaining a MAC address table for up to 2K entries. Designed with surveillance in mind, the switch offers a CCTV mode that isolates PoE ports 1–8 from each other while allowing uplink connectivity to ports 9 and 10 — preventing broadcast storms and enabling extended PoE reach up to 250 meters for long-distance camera placement. LEDs for PWR, LNK/ACT and PoE status provide quick visual diagnostics, and a DIP switch toggles between default and CCTV modes without requiring a reboot.
Practical benefits and use cases
For installers and IT managers, the DN-953 simplifies deployment of IP cameras, access points, and VoIP endpoints where local power outlets are limited. Mode selection helps contain network storms and improves fault isolation. The PD-ALIVE feature enhances compatibility with powered devices, while the built-in surge and electrostatic protections help protect connected gear in harsh environments. The switch’s energy-efficient Ethernet support reduces power consumption during low-usage periods.
Installation and safety notes
Mounting options include desktop placement with rubber feet or wall mounting using M4 screws. The device requires adequate ventilation and should be kept away from moisture. Follow standard precautions: disconnect power before cleaning, verify input voltage (100–240V AC, 50/60Hz) before powering on, and avoid opening the chassis. Grounding via the AC earth or a dedicated ground terminal is recommended for enhanced lightning protection.

FAQ
Q: What PoE standards does the DN-953 support? A: The DN-953 supports IEEE 802.3af and 802.3at PoE standards, delivering up to 30W per port and a total PoE budget of 60W. Use higher-power PDs sparingly to avoid exceeding the aggregate budget.
Q: How does CCTV mode work and when should I use it? A: CCTV mode isolates ports 1–8 from each other while allowing uplink to ports 9 and 10, preventing broadcast storms and improving security. It’s ideal for camera deployments where devices should not communicate with each other directly.
Q: Can the switch be wall-mounted and what are the power requirements? A: Yes, the DN-953 can be wall-mounted using M4 screws. Power input is 100–240V AC, 50/60Hz; ensure correct voltage before powering on and ground the unit for better protection.
Q: What performance specs matter for small networks? A: Key specs include 20Gbps switching capacity, 14.88 Mpps forwarding rate, 2Mbit packet buffer, 9216-byte jumbo frame support, and a 2K MAC address table—suitable for small office and surveillance setups.
Q: Is the DN-953 suitable for outdoor cameras placed far from power outlets? A: Yes, with CCTV mode the DN-953 can extend PoE-powered camera reach up to 250 meters over Ethernet cable, enabling deployments where AC power is unavailable.
Q: How are LEDs and indicators used for troubleshooting? A: PWR (green) shows power status, LNK/ACT (green) indicates link/activity and speed, and PoE (orange) shows PoE presence or port power anomalies. Blink patterns signal traffic or errors.
Q: Are there environmental limits I should heed? A: Operate between 0–40°C with 10–90% non-condensing humidity. Storage ranges are wider; observe ventilation and avoid damp or unstable locations to prevent damage.
