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.
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 pan el view of the S w itch • The AC power connecto r is a standard three-pronged connector that supports the power cord.
without proper heat dissi pation a nd air circulation, system components might overheat, whi c h 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-SX Fiber Module Figure 1-6. 1000BASE-SX two-por t module • Front-panel module. • Connects to 1000BASE-SX devices at full-duplex. • Supports multi-mode fiber-optic cable connections of up to 412 meters in half-duplex or 2 km in full- duplex mode.
LED Indicators The LED indicators of the Switch include Power, Console, and Link/Act. The following shows the LE D indicators for the Switch along with an explanation of each indicator. Figure 1-9. The LED indi cators • Power This indicator on the front panel should be colored amber durin g the Power-On Self Test (POST).
9033693-01 30 ‘Out-of-Band’ connection, meaning that console is connected to the switch using a diffe rent 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.
9033693-01 31 • 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.
9033693-01 32 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.
9033693-01 33 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 int o each port to control broadcast storms.

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 spe ed.
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.
9033693-01 41 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.
If the other device does not have an unused Uplink port, make the connection with a normal straight- through 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.
