Note: It is not necessary to power off the switch before
connecting or disconnecting any UTP cables, as these
actions
will not disrupt the operation of other devices
attached to the switch.
RJ-45 10/100 Mbps Connections
For twisted-pair devices, connect each PC to an RJ-45 port on the
switch with a twisted-pair cable segment, maximum 100 meters
(328 feet). Use Category 3, 4, or 5 cable for 10 Mbps connections,
and Category 5 cable for all 100 Mbps connections.
Note: If an attached device does not support
auto-negotiation, the data rate will be sensed
automatically and the communication mode will
default to half duplex.
Connecting to the Gigabit Uplink Port
The Gigabit uplink port operates at 1000 and 100 Mbps and
supports IEEE 802.3x flow control. Auto-negotiation is used to
select the optimal transmission speed and communication mode.
Use Category 5 or 5e cable of maximum length 100m (328 feet).
You should also test the cable installation for IEEE 802.3ab
compliance. See “1000BASE-T Cable Requirements” on page 14.
