    To minimize the possibility of dropping frames on congested ports, the ELS100-S24TX2M switch provides 128 KB of frame buffering per port. This buffer space is used to queue packets for transmission on congested networks. This is an additional advantage over cut-through switching technology, which drops packets immediately when experiencing collisions.

    These values are retained when the switch experiences power interruptions or is powered down for normal maintenance. Configuration and Management Interfaces The ELS100-S24TX2M switch, or attached stack, can be managed using any of the following methods: • Serial console, out-of-band An RS-232 connection, using a DB-9 connector, is included on the Management Module for system management.

  • Page 26: Auto-Negotiation

    It is not required that the network device being connected to the switch supports auto- negotiation as the ELS100-S24TX2M switch automatically adjusts to the network device’s communication settings. Auto-negotiation is configurable using the console interface menus, the on-board Web agent, or via SNMP.

  • Page 27: Flow Control

    ELS100-S24TX2M switches. Besides balancing the load across each port in the trunk, the additional ports provide redundancy by taking over the load if a port in the trunk should fail. The ELS100-S24TX2M allows up to four RJ-45 ports from a pre-determined selection of ports to be joined together as a trunk.

    Client/Server Network Application To improve workstation performance in a client/server environment, the ELS100-S24TX2M switch can be configured to provide 200 Mbps full duplex Fast Ethernet connections to servers by connecting each to a dedicated switch port (Figure 1-4). Users can be accommodated through connections to hubs, both at 10Mbps and 100Mbps speeds, through 10Mbps switches with 100Mbps uplinks, or through direct connections.

  • Page 32: Local Backbone Application

    Local Backbone Application The ELS100-S24TX2M switch can be used in a local backbone application, connecting network segments together and providing file- server access (Figure 1-5). Workgroup hubs are provided with a single connection to the switch while servers are put on dedicated 100 Mbps ports.
