Unmanaged switch Lanberg RSGE-24P-2GE-2S-250 24 θύρες τοποθέτηση σε rack

The Lanberg RSGE-24P-2GE-2S-250 is an unmanaged PoE+ Ethernet switch with 24 Gigabit PoE+ RJ-45 ports, two Gigabit uplink ports and two SFP Gigabit uplink ports designed for rack mounting. It supplies data and power over structured cabling to devices that comply with IEEE 802.3af/at standards, offering a total PoE power budget of up to 250 W. The device is suitable for installations such as home, business, surveillance, IP/VoIP, cable TV networks and low-voltage systems including alarm, fire and access control systems.

Advantages

The switch combines data switching and PoE power delivery on a single infrastructure, reducing the need for separate power wiring and saving installation time and space. It provides a reliable PoE budget of up to 250 W and supports simultaneous operation of uplink ports independently from the 24 powered ports. A port-priority disconnection logic ensures predictable behavior when the PoE budget is exceeded: ports are turned off starting from the highest numbered PoE port to reduce load while preserving lower-numbered ports. The unit also features an extend mode that allows data (up to 10 Mbps) and PoE+ power transmission up to 250 m on ports 1–24, and integrated surge/discharge protection rated to 4 kV on all ports. Rack-mount ears and mounting hardware are included to simplify installation.

Suitable for

• IP surveillance systems (cameras and NVR integration)
• VoIP phones and business telephony
• Access control, alarm and fire detection systems
• Small and medium office networks requiring rack-mount PoE distribution

How to use

Install the switch in a 19" rack using the supplied mounting ears and screws. Connect the uplink ports to your core network or NVR using the Gigabit RJ-45 or SFP ports as needed. Connect PoE devices (IP cameras, phones, access control panels) to the 24 RJ-45 PoE+ ports. If long-distance operation is required, set the housing toggle to "PoE+ Extend 250 m" to enable extended PoE and data transmission (ports 1–24) at reduced data speed. Ensure connected devices comply with IEEE 802.3af/at standards to receive power from the switch.

Recommendations

For critical devices that must remain powered during PoE budget overloads, connect them to the lowest-numbered PoE ports so they are preserved by the switch's prioritized disconnection logic. Place power-hungry devices and standard devices with known power profiles to avoid unexpected budget exhaustion, and verify cable quality and length when using the extend mode to maintain stable operation.
