Ensure compatibility with your PoE equipment before ordering (PoE budget, IEEE 802.3af\/at standards).\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"section faq\"\u003e\n\n\u003ch2\u003e ❓ Frequently Asked Questions (FAQ)\u003c\/h2\u003e\n\n\u003cdiv class=\"faq-item\"\u003e\n\n\u003cdiv class=\"faq-question\"\u003e Q1: Can this Huawei switch power my IP cameras and IP phones via PoE?\u003c\/div\u003e\n\n                 \u003cdiv class=\"faq-answer\"\u003eYes, absolutely. The S2750-28TP-PWR-EI-AC is specifically designed to power your PoE and PoE+ devices. Its 24 ports support IEEE 802.3af (standard PoE up to 15.4W) and IEEE 802.3at (PoE+ up to 30W per port) standards. This means it can power virtually all IP cameras on the market (Hikvision, Dahua, Axis, Uniview), business IP phones (Cisco, Yealink, Grandstream, Polycom), and Wi-Fi access points (Ubiquiti UniFi, Aruba, Cisco Meraki, TP-Link Omada). The total PoE budget allows you to power multiple devices simultaneously. Automatic detection ensures that no non-PoE equipment will be damaged if connected incorrectly.\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"faq-item\"\u003e\n\n\u003cdiv class=\"faq-question\"\u003e Q2: What is the difference between this PWR-EI model and the standard EI model?\u003c\/div\u003e\n\n                 \u003cdiv class=\"faq-answer\"\u003eThe fundamental difference lies in the presence of PoE+ power. The S2750-28TP-PWR-EI-AC model (with \"PWR\" in the model number) integrates Power over Ethernet Plus functionality on its 24 Fast Ethernet ports, allowing it to power connected devices. The S2750-28TP-EI-AC model (without \"PWR\") has the exact same port configuration but provides no PoE power, only data connectivity. All other management features (VLANs, QoS, security, routing, iStack stacking) are identical between the two versions. Choose the PWR model if you need to power IP cameras, IP phones, or Wi-Fi access points; otherwise, the standard model without PoE is sufficient and less expensive.\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"faq-item\"\u003e\n\n\u003cdiv class=\"faq-question\"\u003e Q3: Is this switch compatible with my network equipment from other brands (Cisco, HP, Dell)?\u003c\/div\u003e\n\n                 \u003cdiv class=\"faq-answer\"\u003eYes, absolutely. Huawei S2700 network switches strictly adhere to all international IEEE and IETF standards, ensuring complete interoperability with equipment from other manufacturers. Standard protocols such as STP\/RSTP\/MSTP (IEEE 802.1d\/w\/s), VLANs (IEEE 802.1Q), LACP (IEEE 802.1ax), 802.1x, LLDP, SNMP, syslog, and PoE\/PoE+ (IEEE 802.3af\/at) are universally supported. Therefore, you can integrate this Huawei switch into an existing network containing Cisco Catalyst, HP ProCurve\/Aruba, Dell PowerConnect, Netgear, Juniper, or any other professional brand of equipment. Cisco, HP, and generic MSA-compatible optical SFP modules are also supported on the uplink ports.\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"faq-item\"\u003e\n\n\u003cdiv class=\"faq-question\"\u003e Q4: Can I create VLANs to separate my guest network from the corporate network?\u003c\/div\u003e\n\n                 \u003cdiv class=\"faq-answer\"\u003eAbsolutely, this is one of the key features of this Enhanced Image managed switch. The S2750-28TP-PWR-EI-AC supports up to 4096 concurrent VLANs compliant with the IEEE 802.1Q standard, more than enough to segment your infrastructure according to your organizational needs. You can easily create a dedicated VLAN for the guest Wi-Fi network, another for VoIP phones, one for security cameras, one for servers, and so on. Configuration is performed via the intuitive web interface or the command-line interface (CLI). Port-based VLAN, MAC-based VLAN, and QinQ functionality offer maximum flexibility. Associate VLANs with QoS policies and ACLs to prioritize and secure each type of traffic according to your IT security policies.\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"faq-item\"\u003e\n\n\u003cdiv class=\"faq-question\"\u003e Q5: Does the switch make noise with fans?\u003c\/div\u003e\n\n                 \u003cdiv class=\"faq-answer\"\u003eNo, that's one of the major advantages of this model: the S2750-28TP-PWR-EI-AC uses natural heat dissipation (fanless design) without any fans. The noise level is therefore 0 dB, meaning it's completely silent. This feature makes it particularly suitable for installation in office environments, meeting rooms, coworking spaces, shops, hotel lobbies, or any other space where noise would be a problem. The metal chassis with integrated heat sinks ensures efficient heat dissipation even under maximum PoE load. This design, with no moving mechanical parts, also significantly increases long-term reliability and reduces the need for preventative maintenance.\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"faq-item\"\u003e\n\n\u003cdiv class=\"faq-question\"\u003e Q6: How can I connect this switch to my existing network and the Internet?\u003c\/div\u003e\n\n                 \u003cdiv class=\"faq-answer\"\u003eConnecting is very simple thanks to the switch's four high-performance Gigabit uplink ports. You have two 1000BASE-X SFP ports for fiber optic modules (SFP-GE-LX-SM, SFP-GE-SX-MM, etc.) and two combo ports that can operate in 10\/100\/1000BASE-T copper or SFP mode. To connect this switch to your internet router, core network switch, or servers, simply use a standard Cat5e\/Cat6 Ethernet cable connected to one of the Gigabit combo ports or insert an SFP module for long-distance fiber optic connections. The 24 Fast Ethernet PoE+ ports are used to connect your endpoint equipment (cameras, phones, access points). Once wired and powered, the switch operates immediately in default mode, and you can then configure it via its web interface by connecting to its management IP address.\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"faq-item\"\u003e\n\n\u003cdiv class=\"faq-question\"\u003e Q7: Is the used product covered by a warranty?\u003c\/div\u003e\n\n                 \u003cdiv class=\"faq-answer\"\u003eYes, although this product is used, we offer a 30-day seller's warranty against any manufacturing defects or hardware malfunctions. This warranty covers replacement or repair in the event of a failure attributable to a defective component. The switch has been rigorously tested by our technicians before shipping: we have checked all Ethernet ports, PoE+ functionality, SFP uplink ports, the management interface, and the power supply. The warranty does not cover damage caused by misuse, improper installation, external power surges, or unauthorized modifications. To preserve your warranty, we recommend using a UPS (Uninterruptible Power Supply) to protect against damage from mains voltage fluctuations. \u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"footer\"\u003e\n\n\u003ch3 style=\"margin-bottom: 15px;\"\u003e 🏢 IT\u0026amp;Office - Your Partner for Professional Network Equipment\u003c\/h3\u003e\n\n         \u003cp\u003e✅ Authentic products | ✅ Professional service | ✅ Secure shipping\u003c\/p\u003e\n\n\u003cp\u003e 📧 Contact us with any questions before purchasing\u003c\/p\u003e\n\n\u003cp style=\"margin-top: 20px; font-size: 12px; opacity: 0.8;\"\u003e © 2025 IT\u0026amp;Office - All rights reserved | Invoice with 0% VAT provided\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e","brand":"Huawei","offers":[{"title":"Default Title","offer_id":52172790923587,"sku":"RDC B5 S2750-28TP-PWR-EI-AC","price":149.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1737\/6915\/files\/678124e23799a91243028867.png?v=1780957206","url":"https:\/\/itandoffice.com\/en\/products\/huawei-s2750-28tp-pwr-ei-ac-optical-ethernet-switch-used-in-good-condition","provider":"IT And Office","version":"1.0","type":"link"}
