PowerSense 20 Slot Modular PoE Hub, BL-8620 The PowerSense 20 slot modular chassis hub may be populated with any combination of PowerSense modules. The individual modules are all hot swappable and fully voltage isolated from each other. These units help reduce Total Cost of Ownership by allowing individual modules to be removed or inserted hot while the chassis and all other modules remain operational Mix and match modules for support of CDP devices, IEEE 48 volt, 24 volt or 12 volt applications within the same chassis. Power IP Phones, Wireless access points, Security cameras and other low voltage devices safely and efficiently with PowerSense. Features: Individual power modules, hot swappable in the 19" rackmount ready chassis, use 1 per powered device Each module is current limited for short circuit protection with power isolation of 1KV between ports for safety Each module has user replaceable fuses for recovery from power surge or lightning damage, quickly repair any module Each module auto-detects the power requirement and offers transparent 10/100Mb and management operations Each module has four diagnostic LED's Mix and match modules for compatiblity with IEEE 802.3af or legacy Cisco CDP powered devices, 24 Volt Protocol or 12 Volt Protocol Condition: Pre-owned in good condition and is pre-loaded with modules.

LinkUp Ethernet Tester With LCD Display The LinkUp Ethernet Tester will provide the first response for troubleshooting network connectivity problems. The unit’s LEDs provide instant basic connection status. The LCD display allows more detailed link analysis through the menu system. Auto-negotiation capabilities can be scrolled through. Power-Over-Ethernet voltages can be read. The LinkBlink test allows the link light on hubs and switches to determine wired port numbers. A data packet loopback test can find failures in pre-run cabling by sending actual data through the cables. The LinkUp case is ergonomically designed for one hand operation and its small size makes storage easy. LinkUp runs on 2 AA batteries and has an auto-power down feature to save battery life.
