Where a traditional router would have one, or at best a few, Fast Ethernet ports, the VH-2402-L3 Layer 3 switch has 24 Fast Ethernet ports and optionally, 2 Gigabit Ethernet ports. Where a traditional router would have one or two high-speed serial WAN connections, the VH-2402-L3 relies upon a Fast Ethernet port to connect to a separate device, which in turn, connects the network to a WAN or the Internet.
distributed infrastructure and a logical management structure, network performance becomes easier to measure and fine-tune. With the completion of the migration of the backbone to Gigabit or higher-performance technologies, the result is inherently scalable and easily evolved for future technologies. This core network will also become the termination point for Virtual Private Networks (VPNs) for remote office access to the enterprise infrastructure.

Optional Redundant Power Supply The VH-2402-L3, 24+2 Fast Ethernet Layer 3 Switch supports the optional Redundant Power Supply to provide automatic power supply monitoring and switchover to a redundant power supply (located in the chassis of the Redundant Power Supply) in case of a failure in the VH-2402-L3’s internal power supply. Fast Ethernet Technology 100Mbps Fast Ethernet (or 100BASE-T) is a standard specified by the IEEE 802.3 LAN committee.
Front Panel The front panel of the Switch consists of LED indicators, an RS-232 communication port, a slide-in module slot, one switched MDI-X/MDI-II uplink port, and 23 (10/100 Mbps) Ethernet/Fast Ethernet ports. Figure 1-1. Front panel view of the Switch • Comprehensive LED indicators display the status of the switch and the network (see the LED Indicators section below).
Rear Panel The rear panel of the switch consists of a slot for the optional Redundant Power Supply and an AC power connector. Figure 1-2. Rear panel view of the Switch • The AC power connector is a standard three-pronged connector that supports the power cord. Plug-in the female connector of the provided power cord into this socket, and the male side of the cord into a power outlet. Supported input voltages range from 100 ~ 240 VAC at 50 ~ 60 Hz.
without proper heat dissipation and air circulation, system components might overheat, which could lead to system failure. Optional Plug-in Modules The VH-2402-L3 24+2-port Fast Ethernet Layer 3 Switch is able to accommodate a range of plug-in modules in order to increase functionality and performance. 1000BASE-T Module Figure 1-5. 1000BASE-TX two-port module • Front-panel module. • Connects to 1000BASE-T devices. • Supports Category 5 UTP or STP cable connections of up to 100 meters.

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 1-9. The LED indicators • Power This indicator on the front panel should be colored amber 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.
‘Out-of-Band’ connection, meaning that console is connected to the switch using a different circuit than that used for normal network communications. So, the console can be used to set up and manage the switch even if the network is down. Local console management uses the terminal connection to operate the console program built-in to the switch. A network administrator can manage, control and monitor the switch from the console program.
• 802.3x Flow Control – if the port is configured in full duplex mode, a MAC PAUSE packet is sent to inhibit the flow of packets to the port for a short amount of time. • Enable Jamming Signal – if the port is configured in half duplex mode, a jamming signal is sent for a short amount of time. Spanning Tree Protocol The VH-2402-L3 switch complies with the IEEE 802.1D Spanning Tree Protocol standard and allows for the blocking of links between switches that form loops within the network.
The VH-2402-L3 supports 6 Port Trunking groups, which may include from 2 to 8 switch ports each, except for a Gigabit Port Trunking group which consists of the 2 (optional) Gigabit Ethernet ports of the front panel. These ports are the two 1000BASE-SX, -TX or GBIC ports contained in a front-panel mounted module. IEEE 802.1Q VLANs IEEE 802.1Q (tagged) VLANs are implemented on the VH-2402-L3. 802.
used to prevent their occurrence, and if that failed, limit their scope. However, with the advent of VLANs, switches are now able to limit broadcast domains better and cheaper than routers. The VH-2402-L3 switch has broadcast sensors and filters built into each port to control broadcast storms. IP Routing IP is responsible for getting packets to the destination specified in the destination address. The task of determining how to get a packet from the source to the destination is referred to as routing.

• Mounting kit: 2 mounting brackets and screws • Four rubber feet with adhesive backing • ESD wrist strap • One AC power cord • Product documentation If any item is found missing or damaged, please contact your local Enterasys Sales Representative for replacement. Installation Use the following guidelines when choosing a place to install the Switch: • The surface must support at least 3 kg. • The power outlet should be within 1.82 meters (6 feet) of the device.
Figure 2-1. Installing rubber feet for desktop installation Rack Installation The VH-2402-L3 can be mounted in an EIA standardsized, 19-inch rack, which can be placed in a wiring closet with other equipment. To install, attach the mounting brackets on the switch’s side panels (one on each side) and secure them with the screws provided. Figure 2- 2A. Attaching the mounting brackets to the switch Then, use the screws provided with the equipment rack to mount the switch on the rack.
Figure 2-2B. Installing the switch on an equipment rack Power on The VH-2402-L3 switch can be used with AC power supply 100-240 VAC, 50 - 60 Hz. The power switch is located at the rear of the unit adjacent to the AC power connector and the system fan. The switch’s power supply will adjust to the local power source automatically and may be turned on without having any or all LAN segment cables connected.
self-test. After approximately 20 seconds, the LED will light again to indicate the switch is in a ready state. • The RDP in use LED When link with redundant power supply, the “RDP in use” LED will blink in orange. • The 100M LED indicator may remain ON or OFF depending on the transmission speed. Power Failure As a precaution in the event of a power failure, unplug the switch. When power is resumed, plug the switch back in.
3. Connecting The Switch This chapter describes how to connect the VH-2402-L3 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. The RJ-45 UTP ports on NICs and most routers are MDI-II. When using a normal straight-through cable, an MDI-II port must connect to an MDI-X port.
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: 1. The 100M LED indicator comes ON for a 100 Mbps and stays OFF for 10 Mbps. 2. The Link/Act LED indicator lights up upon hooking up a PC that is powered on.
If the other device does not have an unused Uplink port, make the connection with a normal straightthrough cable from the Uplink port on the switch to any normal crossed port on the hub. Alternatively, if you have a crossover cable you can save the Uplink ports for other connections and make this one from a crossed port to another crossed port. Figure 3-2.

Appendix B. Flow Control Flow control is a mechanism which allows you to protect the switch from overload conditions and to keep additional traffic off the network when excessive congestion will result. Flow Control for Half- and Full-Duplex Applications Each port of the switch has a transmit queue which buffers frames to be sent out on that port.
Flow control is configurable per port in the Port Configuration Menu of the console menus, using the on-board Web agent, or via SNMP.
