SNMP-24MGB Plus – 20 Port Fiber with
4 Port Combo Managed Switch The SNMP-24MGB Plus is a 24-port Gigabit
L2+Managed Switch including 4-Port Gigabit TP/SFP combo slots and 20-Port
Gigabit SFP slots. This Switch can be used to build high-performance switched
workgroup networks. The switch can be managed through RS-232 serial port via
directly connection, or through Ethernet port using CLI or Web-based management
unit, associated with SNMP agent. In addition, the switch features comprehensive
and useful functions such as QoS, Spanning Tree, VLAN, Port Trunking, Bandwidth
Control, Port Security, SNMP/RMON, IGMP Snooping capability via the intelligent
software. It is suitable for both metro-LAN and office applications. It also
support two input source, 100~240VAC and –48VDC for Power redundancy
application.
Redundancy Power Supply Supported
This switch support two power input 100~200V AC, and –48V DC. Each power
input is capable of powering the entire switch. If one fails, the other power
supply can keep the switch powered up seamless, so as not to interrupt the
normal use of the device. The picture is an example of what a redundant power
supply may look like. The redundant power input is important for this type of
switch , because this fiber switch normally work as the Core Switch for whole
Internet. If the core switch is powered down, whole Internet will down.
Quality Performance and Reliability
The SNMP-24MGB Plus provides security, performance, quality of service and
other network control capabilities. In addition, The SNMP-24MGB Plus can work
from –20 to 60 ? with two input source supported which increase the
reliability of using the switch. It best fit for SMB or entry level enterprise
solution which requires to use Fiber for interconnection.
QoS
The switch supports not only Layer 2 802.1p Priority Queue control, but also
supports programmable higher layer classification and prioritization to enable
enhanced Quality of Service (QoS) support for real time applications based on
information taken from Layer 2 to Layer 4, such as VoIP, Video and Data.
802.1× Access Control Improve Network Security
802.1× features enable user authentication for each network access attempt.
Port security features allow you to limit the number of MAC addresses per port
in order to control the number of stations for each port. Static MAC addresses
can be defined for each port to ensure only registered machines are allowed to
access. By enabling both of these features, you can establish an access
mechanism based on user and machine identities, as well as control the number of
access.
802.1D Compatible, 802.1w Rapid Spanning Tree and 802.1s Multiple
Spanning Tree
For mission critical environments with multiple switches supporting STP, you
can configure the switches with a redundant backup bridge path so transmission
and reception of packets can be guaranteed in event of any fail-over switch on
the network.
