The switch functions can be configured using the WebView™ application, CLI switching
commands, or SNMP.
Each device can be installed as a tabletop unit or installed into a standard 19-inch rack using the
mounting hardware supplied with the rack.
The devices have power supply redundancy capability when connected to an optional external
supply. If the resident power supply fails, the external power supply assumes the entire load of the
device without interruption to network traffic. Each power supply supports its own ac input
connection, which enables each power supply to be connected to a different ac power circuit for
power source redundancy.
1.1.1
Mini-Gigabit Interface Connectors (Mini-GBICs)
The Mini-GBIC installs into a slot to provide 1000BASE-SX or LX network connections. There
are different Mini-GBICs that can provide various types of connectors, such as an MT-RJ
connector, LC connector that supports single-mode fiber-optic cabling, or LC connector that
supports single or multimode fiber-optic cabling. Refer to
Mini-GBICs.
1.2
HALF-DUPLEX/FULL-DUPLEX AUTO-NEGOTIATION
The devices can auto-negotiate the ports' mode of operation (half-duplex or full-duplex) between
two devices according to IEEE 802.3 standards. During Auto-Negotiation, two devices
automatically exchange information about their current operating mode. The Auto-Negotiation
feature targets the maximum capability that can be reached between the two devices. For example,
the devices can adjust to full-duplex operation when the device on the other end of the connection
can also adjust from half-duplex to full-duplex. If the device on the other end of the connection can
only operate in half-duplex mode, then the devices adjust to operate in half-duplex mode.
