D-Link DES-1048 User Manual - Front-Panel Components
D-Link DES-1048 Unmanaged Layer 2 Ethernet Switch
standard twisted pair cabling and are ideal for segmenting networks into small, connected subnets. Each port can
support up to 200 Mbps of throughput in full-duplex mode.
Features
• Forty-eight 10/100 Mbps ports for connections to other LAN switches and hubs, or directly to power
users
• IEEE 802.3 compliant 10BASE-T
• IEEE 802.3u compliant 100BASE-TX
• Full and half-duplex for both 10Mbps and 100Mbps connections. Full duplex allows the switch port to
simultaneously transmit and receive data, and only works with connections to full-duplex capable end
stations and switches. Connections to a hub must take place at half-duplex
• Store and forward switching scheme capability to support rate adaptation and protocol conversion
• Data forwarding rate 14,880 pps per port at 100% of wire-speed for 10Mbps speed
• Data forwarding rate 148,810 pps per port at 100% of wire-speed for 100Mbps speed
• Data filtering rate eliminates all error packets, runts, etc. at 14,880 pps per port at 100% of wire-speed
for 10Mbps speed
• Data filtering rate eliminates all error packets, runts, etc. at 148,810 pps per port at 100% of wire-speed
for 100Mbps speed
• Layer 2 switching based on MAC address
• Address handling: auto-learning, auto-aging
• MAC Address table: Support addresses up to 14K
• A packet buffer size of 6M-bit per device (embedded)
• Auto-negotiation (NWay) between 10Mbps/100Mbps, half-duplex or full duplex for 10/100BASE-T
ports.
Ports
• Forty-eight high-performance NWay Fast Ethernet ports, all of which operate at 10/100 Mbps for
connections to end stations, servers, and hubs. All ports can auto-negotiate between 10Mbps or
100Mbps and full or half duplex.
Front-Panel Components
The front panel of the Switch consists of LED indicators, 48 (10/100 Mbps) Fast Ethernet ports.
