mode powering mode for legacy Power over Ethernet cable devices. The 8 PoE ports
support LLDP power negotiation function or 2-Event classification of IEEE 802.3at PoE
plus, and can therefore deliver up to 30W power per port and 120W per unit at 75°C
operating temperature, to drive the IP cameras for cross-street monitoring or WiMAX
systems for internet accesses at train stations, airports or Hot-spots.
100/1000Mbps DDM SFP transceiver for High Quality Monitoring
The SFP sockets of the JetNet 5310G supports 100Mbps and 1000Mbps SFP type fiber
transceiver with speed detection and independent indication. Moreover, it supports DDM
(Digital Diagnostic Monitoring) type SFP transceivers allowing users to diagnose optical
cable transmission problem through maintenance and debugging of the optical signal
quality by DDM without the need of an extra optical cable analyzer, as a result greatly
saving time and system costs.
Rapid Super Ring (RSR
TM
) Technology
The JetNet 5310G supports Rapid Super Ring technology, which is the 2nd generation of
Korenix Ring Redundancy technology. The recovery time is greatly improved from 30ms
to few ms for both copper and fiber ring. The Ring master can be auto-selected by RSR
engine. The 1st ring port of the R.M. is the primary path while the 2nd ring port of the
R.M. is the block path. Once the primary path fails, the 2nd path will be recovered within
few ms. Besides, the restoration time is also shortened to zero in the R.M. auto-selection
mode.
Comprehensive Redundant Solutions – Multiple Super Ring ( MSR
TM
)
JetNet 5310G also supports advanced Ring technology – M.S.R. (Multiple Super Ring)
which includes various new technologies for different network redundancy applications
and structures. The supported MSR allows JetNet 5310G aggregating up to 5 Rapid
Super rings includes 4 Fast Ethernet plus 1 Gigabit Ethernet rings into one switch. With
the MSR
TM
technology, a node can be configured to multiple rings with the failover time.
In addition, users can extend the ring topology by adding hundreds of JetNet managed
switches to meet the large-scale network needs without compromising the network
speed. The MSR
TM
also allows JetNet 5310G managed switch to easily connect with
core management switches via standard Rapid Spanning Tree Protocol (RSTP) or
through multiple paths or nodes to increase the reliability by RDH
TM
(Rapid Dual Homing)
technology. By integrating MSR
TM
and LACP (Link Aggregation Control Protocol), the
JetNet series can enhance the link ability and increase the overall link capacity. Two or
more Fast Ethernet connections are combined in order to increase the bandwidth and to
create a resilient and redundant link.
