VOLKTEK NSH-580 MANAGED 24-PORT 10/100 + 4 G COMBO L3 SWITCH
2.2 Connectors
The Switch utilizes ports with copper and SFP fiber port connectors functioning under
Ethernet/Fast Ethernet/Gigabit Ethernet standards.
2.2.1 10/100Base-TX
Ports
The 10/100BASE-TX ports support network speeds of either 10Mbps or 100Mbps, and
can operate in half- and full-duplex transfer modes. These ports also offer automatic
MDI/MDI-X crossover detection that gives true “plug-n-play” capability – just plug the
network cables into the ports and the ports will adjust according to the end-node devices.
The following are recommended cabling for the RJ-45 connectors: (1)10Mbps – Cat 3 or
better; (2)100Mbps – Cat 5 or better.
2.2.2 10/100/1000Base-T
Ports
The Switch has four Gigabit 10/100/1000Base-T ports for RJ-45 connectors that have
the same features as the above-mentioned 10/100 ports. The only difference is that the
Gigabit copper ports support network speeds of 10/100/1000Mbps.
These four ports are located next to the four SFP-type fiber slots and each one of these
RJ-45 ports is interchangeable with a corresponding SFP slot. The Gigabit copper port
will have the same number as its corresponding SFP slot. This means that once an SFP
slot is connected, the correspondingly numbered RJ-45 port (25, 26, 27 or 28) will not
function.
2.2.3 SFP slots for SFP modules
The four SFP slots are designed to house Gigabit SFP modules that support network
speeds of 1000Mbps. These slots are interchangeable with the four 1000Base-T ports to
their left and the slots have the same port numbers as their corresponding 1000Base-T
ports. This means that once an SFP slot is connected via an SFP module, the
correspondingly numbered 1000Base-T port (25, 26, 27 or 28) will not function.
