Antaira QMP-1204G-2Q2S-bt-T 12-Port Gigabit Managed PoE++ Switch with 8x PoE++, 2x SFP, 2x 2.5G SFP and Extended Temperature

Where eight high-power devices share a cabinet that also sits on a redundant ring, a twelve-port managed PoE++ switch can replace a PoE injector bank and a separate ring switch. The QMP-1204G-2Q2S-bt-T is a Layer 2 managed gigabit PoE++ switch from Antaira with eight RJ45 ports and four SFP slots, rated -40 °C to 85 °C for DIN-rail mounting.

Each RJ45 port supplies IEEE 802.3bt PoE++ at up to 90 W and also serves 802.3af and 802.3at devices, within a total budget of 240 W at 55 V DC, so the budget rather than the port count sets how many 90 W loads can run together. Two 100/1000 SFP slots and two 100M/1G/2.5G SFP slots carry fibre, on a 20 Gbps switching capacity with 17.9 Mpps forwarding. Management includes 4,096 VLANs, QinQ, eight QoS queues, IGMP snooping, LACP, LLDP and LLDP-MED, port mirroring and 802.1X with RADIUS and TACACS+, accessed over SNMPv3, HTTPS or SSH.

ITU-T G.8032 ERPS recovers in under 20 ms across up to 64 rings, with STP, RSTP and MSTP alongside. The switch adds Link and Service OAM, NTP server and client, SyncE G.8261, OpenDNP3, PROFINET Conformance Class A, EtherNet/IP and IEEE 1588 v2 PTP. Redundant 20 to 60 V DC inputs run it at 15 W without PoE, with 45 to 57 V DC needed for PoE++, and 4 kV ITU K.44 surge protection guards the RJ45 lines.

The IP30 metal case mounts on a DIN rail, with an MTBF of 628,000 hours. Antaira lists CE, FCC, EN 62368-1, EU EMC and LVD compliance and IEC 61850-3, and covers the QMP-1204G-2Q2S-bt-T with its 5-year warranty. We can pre-configure IP addressing, VLANs and ring settings where you ask. The QMP-0804G-2Q2S-bt-T has four PoE++ ports, the QMX-1204G-2Q2S-T is the non-PoE twin, and the QMP-2820G-4X16S-bt-T moves to a 1U rack with 10G uplinks.
