The SNMP management and remote control capability, plus plenty of other functions, along with its high quality, makes for easy and carefree use. The Gigabit module can either be copper or fiber media; it supports not only 100M fiber modules, but also Gigabit modules, such as 10/100/1000M RJ-45 copper ports and Gigabit fiber SC ports with 1000BASE-SX or 1000Base-LX, Gigabit RJ-45 plus GBIC ports, these allow users to increase their network response time at gigabit speeds and with great flexibility. An RS-232 serial port provides an easy way for installation and initial set-up. Non-blocking and maximum wire speed performance are designed on all switched ports, it not only supports Auto-Negotiation, but also AUTO-MDIX function on all switched 24 10/100M RJ-45 ports and two Gigabit Copper ports no matter if in half or full duplex mode. These functions add to the convenience, ease of use, and reduce the matching effort between straight and cross-over line issues. The XP-3242 provides a convenient way to operate a layer 2 management through an Internet browser. User friendly pull-down manual makes learning how to use the XP-3242 easy. It’s also easy to control and easy to monitor. The XP-3242 supports, not only traditional SNMP functions, but also RMON 1,2,3,9 groups for advanced network analysis. Uniquely, it supports both port-based VLAN and Tag-based VLAN to catch-up with the new applications coming in the VLAN age. To increase bandwidth applications, it supports 7 groups with up to 4 ports Trunk; and these trunk ports are with fair-over function to provide redundant back-up when one or some of the ports are in malfunction. Total front access design and fully LED status display also adds to the ease of installation, inspection and maintenance efforts at rackmount environments. In addition an extra LED display reflects the fan status to help prevent over-heating issues, if the fan were to malfunction; thus adding to the protection of the unit and the investment. FEATURES ..
