2.2 Product Description
Multilink ML810 Managed Edge Switches provide configurability in an entry-level
industrial-grade package. The high performance ML810 base unit comes with four 10/100
copper ports (which may be either regular or PoE). Up to 4 100Mb fiber ports or up to four
more 10/100 copper ports or combinations, may also be configured. In addition, one or
two Gb ports may be configured as 10/100/1000 copper or SFP fiber in any ML810 base
unit.
Multilink ML810 comes with the best-of-breed MultiLink ML810 Managed Edge Switch
firmware.
Multilink ML810s are ideal for building a switched, hardened Ethernet network
infrastructure, connecting edge devices such as PLCs and IEDs with upstream switches or
routers. Designed for use in industrial applications such as factory floors and control
cabinets, industrial video surveillance systems with PoE, power utility substations, tariffed
carrier field facilities, or transportation and oil and gas, the rugged Multilink ML810 handles
stressful workloads (mixes of bursty data traffic and priority streaming traffic) as well as
harsh environmental conditions.
The ML810 metal case serves as a heat sink and a sealed-case design enables the unit to
operate in harsh Industrial grade environments and achieves high EMI noise immunity.
Heavy duty Ethernet Switch jobs are readily accommodated with an extended
temperature rating of -40˚C to 60˚C by the UL Component Parts method, or -40˚C to 85˚C
by the IEC 60068 Type-Test method. With options such as several popular DC power input
types, AC power and DIN-Rail mounting, the hardened Multilink ML810 is a "multi-purpose"
Industrial Ethernet Switch.
The ML810 managed switches also provides a PoE option via power –inside PoE base unit
(ML810P-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. Multilink ML810 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.
Multilink ML810 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 ML810.
Alarm Relay contacts provided on each Multilink ML810 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.
