port compliant with IEEE 802.3u. If the other port is not IEEE802.3u compliant, the port defaults to
half-duplex (10 Mbps mode). Users can operate the communication speed and duplex mode manually.
Flow Control
Enables or disables Flow Control. Flow control is a protocol preventing packets from being dropped
by reducing the amount of traffic to a level that can be accommodated. If enabled on both ends of a
connection, it prevents the sender from sending data until the receiver can accept it. This switch
complies with the IEEE802.3x flow control standard.
Gigabit Ports
The port type can be chosen for the two-gigabit ports on each switch. The default is the port using
the RJ-45 interface. Select the GBIC interface by plugging a GBIC connector. The GBIC interface has
higher priority than the shared RJ-45 interface.
Enabling the GBIC connector for a Gigabit Ethernet port disables the built-in 1000BASE-T
port. GBIC ports do not support Auto Negotiation. Manually configure the GBIC port. The
default values are 1000 Mbps, full duplex.
Five commands are available on the menu: Set Admin Status, Set Flow Control, Set Mode, Next Page,
and Previous Page.
Set Admin Status: Enable or disable the admin. status of a port.
Set Flow Control: Enable or disable flow control of a port.
Set Mode: Manually configure the speed and operation mode of a port. The first 24
ports have two speeds, 10 or 100Mbps while the last two gigabit ports
has three speeds, 10, 100, and 1000Mbps. Two operation modes, half
and full duplex, are available for 10 and 100Mbps but only full duplex is
allowed on 1000Mbps. When the command is issued, two short keys, A
and N, are displayed. The A stands for automatic and N stands for non-
automatic. Choose N to manually configure a port.
