using CAT5 or CAT5E cord, including high-speed work stations, servers, routers,
concentrators or other switches;
Notes:
(1) CAT3 and CAT4 cord can only allow 10Mbps data flow, while CAT5 and CAT5E can
have 100Mbps;
(2) 10/100Base-T ports can auto-negotiate using either direct-connect cable or crossover
cable.
Furthermore you can set the 10/100Base-T ports to half-duplex mode or full-duplex mode, 10M
or 100M and compose the two configurations at your intention. You can also set the ports to be
speed and duplex auto-negotiable according to IEEE802.3u standard. When a port is set to be
auto-negotiable, it will learn the speed and duplex info of the connected device and inform it its
own info. If the connected device is also auto-negotiable, the port will tune to the best
connection, i.e., set the speed to be the maximum both devices can support; and if the
connected device supports full-duplex, it will also use full-duplex.
More Info:
According to IEEE802.3u standard, the auto-negotiation process needs to create connections
for both devices to communicate and negotiate with each other, we recommend users to set
both connecting ports to be auto-negotiable, thus to make sure the auto-negotiation function is
able to tune the connection to the best status.
1.5.2 Extendible slots
The iSpirit 3026 switch have two extendible slots, which can use 100M single mode or multiple
mode fiber module, 1000M single mode or multiple mode fiber module or 10/100/1000Base-T
copper ports (shown in a previous chapter). The fiber configuration is shown in Table1-2.
