Ports & Connectivity

The switch provides 48 x 10/100/1000BASE-T PoE ports that supply power directly to devices compliant with IEEE 802.3af and 802.3at. Ports 1 to 48 are PoE-enabled and share a total budget of 370 W. Four Gigabit GbE/SFP combo ports allow a choice between copper and fiber uplinks at 100/1000 Mbps.

All twisted-pair ports support Auto MDI/MDIX, automatically compensating for cable crossovers. The port standards include IEEE 802.3, 802.3u, 802.3ab, and 802.3z. Network cables supported are UTP Cat. 5 and Cat. 5e up to a maximum length of 100 m. The duplex mode operates in full-duplex or half-duplex at 10/100 Mbps and exclusively in full-duplex at 1000 Mbps.

Performance & Architecture

The switching capacity is 104 Gbps with a maximum forwarding rate of 77.4 Mpps for 64-byte packets. The transmission method is store-and-forward, ensuring complete frame inspection before forwarding. The MAC address table supports 16K entries, supplemented by 256 static MAC addresses.

A 12 Mbit packet buffer handles data during traffic spikes. The main memory consists of 128 MB DDR3, with 32 MB flash memory. IEEE 802.3az Energy Efficient Ethernet and IEEE 802.3x flow control are implemented on the ports. The MTBF is rated at 236,406 hours.

Chassis & Power Supply

The switch is housed in a 1U black chassis measuring 440 x 430 x 44 mm and weighing 6.26 kg. Cooling is provided by three fans, which generate 52.4 dB(A) in high-speed mode and 47.6 dB(A) in low-speed mode. Mounting options include desktop placement or 19-inch rack installation; mounting brackets are included.

Power is supplied via an internal universal power supply with 100 to 240 V AC at 50/60 Hz. Maximum power consumption with PoE enabled is 478.9 W at 100 V or 454.1 W at 240 V. Without PoE, it drops to 54 W at 100 V or 54.4 W at 240 V. In standby mode, the switch consumes 32 W at 100 V or 31.6 W at 240 V.

Certifications & Environmental Conditions

The switch holds certifications including CE Class A, VCCI Class A, FCC Class A, BSMI, CB, UL, LVD, and CQC. The permissible operating temperature ranges from -5 to 50 °C, while the storage temperature ranges from -20 to 70 °C. Both operating and storage conditions specify a relative humidity of 0% to 95%.
