10BASE-TX Network
When
connecting
a
10BASE
‐
TX
segment
to
one
of
the
RJ45
fixed
ports
(1
through
48)
on
both
the
B2G124
‐
48P
and
the
B2H124
‐
48P,
ensure
that
the
network
meets
the
Ethernet
network
requirements
of
the
IEEE
802.3
‐
2002
standard
for
10BASE
‐
TX.
Refer
to
the
Cabling
Guide
for
details.
100BASE-TX Network
When
connecting
a
100BASE
‐
TX
segment
to
one
of
the
RJ45
fixed
ports
(1
through
48)
on
both
the
B2G124
‐
48P
and
the
B2H124
‐
48P,
use
Category
5
UTP
cabling.
The
switch
at
the
other
end
of
the
twisted
pair
segment
must
meet
IEEE
802.3
‐
2002
100BASE
‐
TX
Fast
Ethernet
network
requirements
for
the
switches
to
operate
at
100 Mbps.

The
Mini
‐
GBIC
port
sockets
on
the
B2G124
‐
48P
and
B2H124
‐
48P
enable
you
to
vary
the
type
of
1
‐
Gbps
port
connection.
The
device
at
the
other
end
of
the
segment
must
meet
the
same
Gigabit
Ethernet
requirements
for
the
connected
devices
to
operate
at
1
‐
Gigabit
speed.
At
the
printing
of
this
document
there
were
five
Mini
‐
GBICs
available
that
support
fiber
‐
optic
connections,
as
listed
below,
and
one
that
supports
a
copper
connection

Note:
If a port is to operate at 100 or 1000 Mbps, Category 5 cabling must be used.
Category 3 cabling does not meet the 100 or 1000 Mbps specifications. For 10 Mbps
operation only, Category 3, Category 4, or Category 5 cabling can be used. Refer to
100BASE-TX Network
(page 2-2) and
1000BASE-T Network
(page 2-3) for information
about 100BASE-TX and 1000BASE-T networks and cabling.
Note:
When using the fixed ports on the switch for 100 Mbps operation use Category 5
UTP cabling with an impedance between 85 and 111 ohms for 100 Mbps operation.
Depending on the switch used, the fixed switch ports are capable of operating at 10 or
100 Mbps (B2H124-48P
),
or
at
10, 100, or 1000 Mbps (B2G124-48P
)
. This is
accomplished when Auto-Negotiation is enabled, allowing the switch to automatically
sense the transmission speed of the other device and adjust for the speed accordingly.
