The 6KQE managed switches also provides a PoE option via power –inside PoE base unit (6KQEP-48VDC) on Slot A and allows the users to utilize up to 4-ports of PoE to support 802.3af Powered devices. See details for PoE base unit in sec 5.2. The Power Sourcing Equipment (PSE) is fully compatible with Powered Devices (PD)(e.g wireless access points, IP phones) that comply with the IEEE 802.3af PoE standard. The PoE switch ports have an auto-sensing algorithm, so that they provide power only to 802.3af, PoE end devices. PoE is managed by a multi-stage handshake to protect equipment from damage and to manage power budgets .The PoE ports will discontinue supplying power when the PoE powered devices are disconnected. This feature supports the 802.3af PoE PSE standard for over-current protection, under-current detection, and fault protection.

High performance features include non-blocking unicast traffic speed on all ports and 802.1p QoS Traffic Prioritization. Magnum 6KQE switches are “plug-and- play” and are designed for use in connecting edge devices such as PLCs, IEDs and PoE video cameras with upstream switches and routers where a mix of bursty data traffic and priority streaming traffic for video surveillance and cell-tower applications are present.

Magnum 6KQE Managed Edge Switches have heavy-duty aluminum cases and are readily available with standard Industrial grade 24VDC power. Alternative internal DC power options are available. Internal AC power and DC power input types may be 12V, 24V, 48V, 125V, 250V and dual source DC input is optional on the 6KQE.

Alarm Relay contacts provided on each Magnum 6KQE Switch monitor the hardware and software through traps, providing a record of any losses of power signals and other user- defined software events. See Section 3.5 for details.

2.2.1Packet Prioritization, 802.1p QOS

Quality of Service means providing consistent predictable data delivery to users from datagram paths that go all across a network. As a LAN device, the Magnum 6KQE can do its part to prevent any QOS degradation while it is handling Ethernet traffic through its ports and buffers.

The Magnum 6KQE switching hardware supports the IEEE 802.1p standard and fulfills its role in support of QOS, giving packet processing priority to priority tagged packets according to the 802.1p standard. In addition to hardware support for QOS, the MNS software (R2) supports two priority queues that can be shared across the eight levels of defined packet priorities for application-specific priority control by the user through software configuration settings.
