The 6KL managed switches also provides a PoE option via power –inside PoE
base unit (6KLP-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 5.1.11. 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 6KL 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 6KL Managed Edge Switches have heavy-duty steel 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 6KL.
Alarm Relay contacts provided on each Magnum 6KL 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.
2.2.1
Packet 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
6KL can do its part to prevent any QOS degradation while it is handling Ethernet traffic
through its ports and buffers.
The Magnum 6KL 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.
