❓Frequently Asked Questions (FAQ)
Q1: What is the difference between PoE and PoE+ on this manageable network switch?
The GS1920-24HP supports the IEEE 802.3at PoE Plus (PoE+) standard, which provides up to 30W per port, compared to 15.4W for the standard PoE 802.3af. This higher power allows for powering demanding devices such as motorized PTZ IP cameras, high-performance dual-band Wi-Fi access points, color screen VoIP phones, or access control terminals. The total PoE budget of 375W allows you to connect multiple devices simultaneously to your Gigabit switch.
Q2: Is this Zyxel Ethernet switch compatible with my existing network equipment?
Yes, this smart switch is fully compatible with all standard network equipment on the market. It supports auto-negotiable connection speeds of 10/100/1000 Mbps on each RJ-45 port, automatically adapting to your devices. The 4 combo SFP ports accept fiber optic modules for long-distance links. Compatible with IEEE 802.3, 802.3u, 802.3ab, 802.3z, 802.3af, and 802.3at standards, it integrates perfectly into any existing professional network infrastructure.
Q3: How to manage and configure this smart managed Layer 2 switch?
The GS1920-24HP offers several flexible network management methods. The intuitive Web interface allows for complete configuration via browser without additional software. Advanced network administrators can use SNMP v1/v2c/v3 for integration into their monitoring tools, SSH for a secure command line connection, or the Zyxel ZON utility. Layer 2 features include VLAN creation to segment your network, Quality of Service (QoS) to prioritize critical traffic, port mirroring for traffic analysis, and much more.
Q4: Can I mount this switch in a 19-inch rack patch panel?
Absolutely! This network switch has a standard 1U format for mounting in a 19-inch rack. Its dimensions (440 x 330 x 44.5 mm) meet industry professional standards. The complete rack mounting kit with mounting ears and screws is included in this sale, allowing for immediate installation in your patch panel or server cabinet. The switch can also be used in a free-standing position on a flat surface thanks to its built-in anti-slip feet for desktop installation.
Q5: What is the actual power consumption of this Zyxel PoE+ switch?
The consumption of the GS1920-24HP varies depending on the use of the PoE ports. Without powered equipment, the base consumption of the switch is around 40-50W. With all PoE ports active at maximum, consumption can reach 463.5W (including the PoE budget of 375W plus the switch's own consumption). The energy-saving function optimizes consumption by automatically disabling unused ports and adjusting PoE power according to the actual needs of each connected device, thus reducing your energy bill.
Q6: What are the main network security features available?
This managed Layer 2 switch incorporates several essential security mechanisms to protect your infrastructure. MAC address filtering allows you to control which devices can connect. IP address-based access control lists (ACLs) permit or block traffic according to specific rules. Storm Control protects against flooding attacks (broadcast, multicast, unicast). 802.1X authentication can be configured for advanced access control. VLAN segmentation isolates different services and departments to limit the spread of potential threats on your corporate network.
Q7: Is this used network equipment suitable for an IP surveillance system?
Absolutely! The GS1920-24HP is an excellent choice for powering and connecting high-resolution IP surveillance cameras. With its PoE+ budget of 375W and 24 powered ports, you can connect up to 24 IP cameras depending on their individual consumption. QoS features ensure video stream priority, IGMP Snooping optimizes multicast streaming, and VLANs allow for isolating surveillance traffic from the rest of the network. SFP ports provide the option to connect the switch to a remote NVR recorder via fiber optic for extended installations.
