Removing the module
To remove a module:
1 If the switch is already operational, disconnect it from the main
power supply.
2 Follow the instructions in “Avoiding damage to the circuit
board” above.
3 Unscrew the screws securing the module.
4 Pull the module gently to disengage the connectors fully from
the socket on the motherboard. Slide the module out com-
pletely.
5 Cover the empty module port with the plate and secure using
the screws.
Connecting Other Devices
Introduction Incorrect cabling is often the cause of network configuration prob-
lems
Connecting the
management PC
To manage the switch from a PC connected directly to the switch, the
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.
Connecting a device to the
SC ports
To connect a fast access device (such as a server) to the switch:
1 Ensure that the server has a 100Mbps (100Base-FX) network
interface card installed. If not, use your network interface card’s
documentation to install and configure it correctly.
2 Use a 62.5/125 µm or 50/125 µm multimode fiber cable. Ensure
that the cable has an SC connector to fit the switch ports, and an
appropriate connection to match the interface on the server (ST
or SC connectors).
The total attenuation in the link, including connectors and
patch fibers, must not exceed 11dB. For 62.5/125 µm fiber this
means, in most cases, the length of a full-duplex link cannot
exceed 2000 meters (approximately 6500 feet).
