Up to 8 Switches may be stacked and managed as a unit with a single IP address. Management for the entire stack is done through the Master Switch. You may add Switches later as needed. The Switch can also be grouped in a stack as a slave with the D-Link DGS-3212SR or DGS-3312SR Switch (acting as the Master). Fast Ethernet Technology 100Mbps Fast Ethernet (or 100BASE-T) is a standard specified by the IEEE 802.3 LAN committee. It is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while maintaining the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Ethernet protocol. Gigabit Ethernet Technology Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full duplex, flow control, and management objects, but with a tenfold increase in theoretical throughput over 100Mbps Fast Ethernet and a one hundred-fold increase over 10Mbps Ethernet. Since it is compatible with all 10Mbps and 100Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting a company's existing investment in hardware, software, and trained personnel. 2 DES-3226S Layer 2 Fast Ethernet Switch User's Guide 2 Unpacking and Setup This chapter provides unpacking and setup information for the Switch.

This forms an eightSwitch stack that can then be managed and configured as thought the entire stack were a single Switch. The Switch stack is then accessed through a single IP address or alternatively, through the master Switch's serial port (via the management station's console and the Switch's Command Line Interface). The stacking module's LED indicators are described below. LED Indicators Link Active Off ­ No Link Solid Green ­ Link Off ­ No Activity Blinking Green ­ Activity 15 DES-3226S Layer 2 Fast Ethernet Switch User's Guide LED Indicators The LED indicators of the Switch include Power, Console, and Link/Act. The following shows the LED indicators for the Switch along with an explanation of each indicator. Figure 3 - 12. The LED Indicators · · · Power This indicator on the front panel should be lit during the Power-On Self Test (POST). It will light green approximately 2 seconds after the Switch is powered on to indicate the ready state of the device. Console This indicator is lit green when the Switch is being managed via out-of-band/local console management through the RS-232 console port using a straight-through serial cable. Act/Link/Speed These indicators are located to the left and right of each port. The right side indicator will light when the port has a link of 100 Mbps; the Link indicator will not light for 10 Mbps links. The LEDs blink whenever there is reception or transmission (i.e. Activity--Act) of data occurring at a port. Stacking Module LED Indicators The Switch's current order in the Switch stack is also displayed on the Stacking Module's front panel - under the STACK NO. heading: Figure 3 - 13. Stacking Module LED Indicators The Link and Act LEDs have the same function as the corresponding LEDs for the Switch's Ethernet ports. The Link LED lights to confirm a valid link, while the ACT LED blinks to indicate activity on the link. The Stack No. seven-segment LED displays the unit number assigned to the Switch. The numeral 1 in the display indicates that the stacking module is in the process of determining the stack status and has not yet resolved the Switch's unit number. If the master Switch fails, a new master Switch should be configured for the stack until the failure can be fixed. Any time the composition of a stacked Switch group changes, all Switches in the stack will reboot automatically and the master-slave relationship and stack number will be renegotiated. A link failure will require reconnecting the stacking ports to work around the failed link. 16 DES-3226S Layer 2 Fast Ethernet Switch User's Guide 4 Connecting the Switch This chapter describes how to connect the DES-3226S to your Fast Ethernet network. Switch to End Node End nodes include PCs outfitted with a 10, 100 or 10/100 Mbps RJ-45 Ethernet/Fast Ethernet Network Interface Card (NIC) and most routers. An end node can be connected to the Switch via a two-pair Category 3, 4, 5 UTP/STP straight cable (be sure to use Category 5 UTP or STP cabling for 100 Mbps Fast Ethernet connections. Connections to 1000 Mbps Gigabit ports on the 1000BASE-T Module must also use Category 5e). The end node should be connected to any of the twenty-four ports of the DES-3226S. Figure 4 - 1. Switch connected to an End Node The LED indicators for the port the end node is connected to are lit according to the capabilities of the NIC. If LED indicators are not illuminated after making a proper connection, check the PC's LAN card, the cable, Switch conditions, and connections. The following LED indicator states are possible for an end node to Switch connection: · · The 100 LED indicator comes ON for a 100 Mbps and stays OFF for 10 Mbps. The Link/Act LED indicator lights up upon hooking up a PC that is powered on. Switch to Hub or Switch
