5. OPTIMIZING CONFIGURATION
5.1 Prior to Installation
Before installing the Switch
and connecting network devices, it
is important to plan the new network layout. Consider:
• Dedicated Bandwidth: File servers and other high-traffic
hardware can improve if they have their own direct connection
with dedicated 10 or 100Mbps bandwidth.
• Full-Duplex: Determine which devices would benefit from a
Full Duplex connection and check that they support it.
• Fast Ethernet: 100Base-TX and 100Base-FX have different
rules for cable and distance. Make sure these are followed.
• Auto-Negotiation: Devices with different speeds may be
easily swapped when the other end of the cable is fixed to a port
with auto-negotiation.
• Crossover Uplink: Another hub can be attached to Switch
using UTP Crossover function.
5.2 Half- and Full-Duplex
The Switch support both Half- and Full-Duplex modes for
10Base-T, 100Base-TX, and 100Base-FX. Half-Duplex mode is
the traditional data transfer mode: one station sends data while
other devices wait for the first to finish.
Full-Duplex is the simultaneous transmission and receiving of
data. It is only possible between two devices with a dedicated
link (e.g., switch-to-switch, switch-to-PC). Both of the devices
must be capable of, and set to, Full-Duplex
The 100Base-FX port set Half- or Full-Duplex mode through
module's DIP-switch. 100Base-TX ports use auto-negotiation to
detect and set the line's operating mode.
