Connecting a device to the

To connect a workstation compatible with IEEE 802.3 (Ethernet Ver-

RJ-45 ports

sion 1.0 and 2.0) or a fast access device (such as a server) to the

 

switch’s RJ-45 ports using UTP cable (Category 5):

 

1 Make sure that the device has a 100Mbps (100Base-FX or 10/

 

100Base-TX) network interface card installed.

 

If not, use your network interface card’s documentation to

 

install and configure it correctly.

 

2 If your workstation is fitted with an RJ-45 interface then there is

 

no problem. However, it is possible to attach to other connector

 

types using an appropriate adapter. For example, use a UTP/

 

10Base-FL adapter for fiber connections

 

3 Connect one end of the UTP cable to an RJ-45 port on the

 

switch.

 

 

 

According to IEEE 802.3, the cable length must not exceed 100

 

meters (approximately 325 feet).

 

4 Connect the other end to the 100Base-TX connection on the

 

device.

 

 

Connecting the

To manage the switch from a PC connected directly to the switch, the

management PC

PC must not use frame tagging. To manage the switch from a PC with

 

IEEE 802.1Q tagged frames, management must be through a device

 

which untags the frames.

Cable for the Console Port

If you connect a PC (via the Console Port), then use a null-modem ca-

 

ble.
