• Filtering and forwarding incoming and outgoing traffic to the appropriate
route without slowing down the traffic
• Store-and-forward forwarding mode to minimize erroneous packets on the
network
• Autonegotiation on each port with the following four modes:
— 10BASE-T half-duplex
— 10BASE-T full-duplex
— 100 BASE-TX half-duplex
— 100 BASE-TX full-duplex
• Back pressure in half-duplex mode
• Automatic polarity detection and correction
• Easy plug-and-play installation with no software to configure, which saves
time and minimizes the potential for configuration errors
• A comprehensive LED indicator panel for monitoring switching condition
and individual port status
• Conformity to the IEEE 802.3u 100BASE-TX Class II standard
• Conformity to the 802.3 10BASE-T standard
• Per port buffer sizes, as shown in Table 1-3
• MDI/MDI-X push button switch for uplink capability
Note: In order for ports on a BayStack 70 Series 10/100 Ethernet Switch to
operate in full-duplex mode, the switch must be connected to a device that
supports autonegotiation in accordance with the IEEE 802.3u specification.
