DES-1048G Fast Ethernet/Gigabit Ethernet Switch User’s Guide Ethernet NIC’s are able to perform 10 times the number of operations in the same amount of time. In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost- effective method to take advantage of today and tomorrow’s rapidly improving switching and routing internetworking technologies. -
Page 11: Des-1048G 10/100/1000 Mbps Stand-Alone Switch
DES-1048G 10/100/1000 Mbps Stand-alone Switch General Description of Switch The DES-1048G is a stand-alone unmanaged switch. It is equipped with forty-eight ports providing dedicated 10 or 100 Mbps bandwidth. These ports can be used for connecting PCs, servers, and hubs. The forty-eight dual speed ports use standard twisted-pair cabling and are ideal for segmenting networks into small, connected subnets. -

DES-1048G Fast Ethernet/Gigabit Ethernet Switch User’s Guide Switch to Hub or Switch These connections can be accomplished in a number of ways. The most important consideration is that when using a normal, straight-through cable, the connection should be made between a normal crossed port (Ports 1–48) and an uplink (MDI-II) port. -
Page 21: Connecting To Network Backbone Or Server
DES-1048G Fast Ethernet/Gigabit Ethernet Switch User’s Guide Connecting to Network Backbone or Server The optional GBIC fiber optic ports are ideal for uplinking to a network backbone or network server via 1000BASE-SX, 1000BASE-LX or 1000BASE-LH fiber optic cable. These ports operate at 1000 Mbps in full duplex mode only. GBIC port modules can be installed or taken out without powering off or disconnecting the Switch. -
Page 22: Switch Management
Configuring the Switch is discussed in detail. Local Console Management Local console management involves the administration of the DES-1048G Switch via a direct connection to the RS-232 DTE console port. This is an Out-Of-Band connection, meaning that it is on a different circuit than normal network communications, and thus works even when the network is down. -
