Single-Port 1000BASE-SX Gigabit Module Using multimode fiber optic cable, the 1000BASE-SX port can be connected to a remote site up to 550 m (1805 ft) away. The 1000BASE-SX Gigabit module operates at 1 Gbps, with support for full-duplex mode and flow control. This module is fitted with an SC connector, but you can attach an ST plug to the switch using the SC-ST Converter (Part Number: ST5002). Note: If the attached device does not support auto-negotiation, you will have to manually configure the other device to full duplex and no flow control. Optional 1000BASE-LX Module (VM2512A-1LX-SC-S) RXTX VM2512A-1LX-SC-S 1000BASE-LX Singlemode Module Figure 1-7. Single-Port 1000BASE-LX Gigabit Module Using single-mode fiber optic cable, the 1000BASE-LX port can be connected to a remote site up to 5 km (16404 ft) away. The 1000BASE-LX Gigabit module operates at 1 Gbps, with support for full-duplex mode and flow control. This module is fitted with an SC connector, but you can attach an ST plug to the switch using the SC-ST Converter (Part Number: ST5002). Note: If the attached device does not support auto-negotiation, you will have to manually configure the other device to full duplex and no flow control. Optional 1000BASE-X GBIC Module (VM2512A-1GX-GBIC) 1000BASE-X GBIC Module VM2512A-1GX-GBIC Figure 1-8. Single Port 1000BASE-X GBIC Module Description of Hardware 1000BASE-SX GBIC transceivers provide one short-wavelength (850 nm) Gigabit port that can be used for a high-speed backbone or server connection. This port can be connected to a site up to 220 m (722 ft) away with 62.5/125 micron multimode fiber cable, or up to 500 m (1641 ft) with 50/125 micron multimode fiber cable. 1000BASE-LX GBIC transceivers provide one long-wavelength (1300 nm) Gigabit port that can be used for a high-speed backbone or server connection. This port can be connected to a site up to 5 km (16404 ft) away with single-mode fiber cable. 1000BASE-LH GBIC transceivers provide one long-wavelength (1550 nm) Gigabit port that can be used for a long-haul connection to a remote location. This port can be connected to a site up to 70 km (43.5 miles) away with single-mode fiber cable. Caution: Install only 5 V GBIC transceivers into the module slots Optional 1000BASE-T Module (VM2512A-1GT) VM2512A-1GT 1000BASE-T Module Figure 1-9. Single-Port 1000BASE-T Gigabit Module Using Category 5 or 5e twisted-pair cable you can connect to another device up to 100 m (328 ft) away. The 1000BASE-T module operates at 10, 100, or 1000 Mbps, full duplex, and supports auto-negotiation of speed and flow control. Note that you should first test the cable installation for IEEE 802.3ab compliance. See “1000BASE-T Cable Requirements” on page B-3. If the attached device does not support auto-negotiation, you will have to manually configure the other device to match the speed and duplex mode with no flow control. Optional 10/100BASE-TX Module (VM2512A-1TX) 10/100BASE-TX Module VM2512A-1TX Figure 1-10. 1-Port 10/100BASE-TX Module Using Category 3, 4, or 5 twisted-pair cable for 10 Mbps links or Category 5 twisted-pair cable for 100 Mbps links, you can connect to another device up to 100 m (328 ft) away. The 10/100BASE-TX module operates at 10/100 Mbps, full and half duplex, and supports auto-negotiation of speed and flow control.
