Page 8 High-Performance / Cost-effective / Telecom class Gigabit solution for Enterprise backbone and Data Center Networking The GE Security Managed Switch is a L2/L4 Managed Gigabit Switch. Since Gigabit network interface had become the basic equipment and requirement of Enterprise and Network Servers, with 48Gbps switching fabric, the Managed Switch can handle extremely large amounts of data in a secure topology linking to a backbone or high capacity servers.
Page 9 8-ports for trunking, and it supports fail-over as well. Excellent Traffic Control GE Security GE-DSG-244/GE-DSSG-244 series is loaded with powerful traffic management and QoS features to enhance services offered by telecoms. The functionality includes QoS features such as wire-speed Layer 4 traffic classifiers and bandwidth limiting that are particular useful for multi-tenant unit, multi business unit, Telco, or Network Service Provide applications.
Page 10 High-Speed HDMI-like interfaces for stacking with the series of switches. By applying the GE-DSSG series Switch, up to 16 units, 384 fiber-optical ports can be managed by a stacking group and you can add ports and functionality as needed.
Page 11 The stacking technology also enables the chassis-based switches to be integrated into GE-DSSG series Managed Switch but without the expensive up-front cost.

The following list of approved GE Security SFP transceivers is correct at the time of publication: • SFP1000SX-220 SFP (1000BASE-SX SFP transceiver / Multi-mode / 850nm / 220m~550m) •...
Page 34 Chapter 2: Installation NOTE: It is recommended that only approved GE Security SFP transceivers be used on the Managed Switch. If you insert an SFP transceiver that is not supported, the Switch may not recognize it. Before connecting the other switches, workstations or Media Converter: 1.
Page 35 You can add GE-DSSG-244 series switches as needed to support more network clients, knowing that your switching fabric will scale to meet increasing traffic demands.
Page 36 Before attempting to connect stacking ports, verify that you have the required stack cables. The following cables are used to connect stacked switches: • CB-STX50: 50cm, Short stack cable -used to connect adjacent GE-DSSG-244 series switches. • CB-STX200: 200cm, Long / Redundant stack cable - used to connect the top and bottom GE-DSSG-244 series switches of a stack.

NOTE: The stack port is for management and data packets to be transmitted between other GE-DSSG-244 series stackable switches, the stack ports can't be configured with Layer 2 features via management interface. STEP-4: Power up the stack switches.
Page 38 Stack ID Master LED STEP-6: When a GE-DSSG-244 series Switch is added to the stack, a Switch ID is automatically assigned to the GE-DSSG-244 series Switch. Choosing a different Switch ID on the Stack Configuration page can modify the automatic SID assignment.
