1. Product overview |
- !-RexQ28P is a 2 layer intelligentPoE (Power over Ethernet) switch withthe highly efficient switch engine of 12.8Gbps that supports various functions and performance.
- 24 PoE ports comply IEEE 802.3af standard and support 15.4 W electricity. !-RexQ28P switch manages maximum 16384 MAC addresses and support IEEE 802.1D/w/s standard STP that prevent disturbance due to network’s loop. As an advanced 2 layer switch it support not only 4094VLANs, 8 ports/ 12groups ofLAG, port mirroring, IGMP snooping but also DHCP relay, NTP/SNTP, LACP andself-loop isolation. Those functions assist powerful and efficient network management method.
- To cope with intelligent internet service, it supports advanced traffic management such as IEEE 802.1p CoS, Quality of Service (SP/WRR /DRR, 8queues per port), bandwidth control, storm control and access list control. It can be managed through CLI, Telnet and SNMP.In order to extend security of system maintenance, server based authorization function SSH v1/v2, RADIUS/ TACACS+, for an example is supported. And also installation of a fan that automatically controlled by the surrounding temperature improves the safety of product and reduces the electric power consumption, noise level.
- !-RexQ28Pis the intelligent switch with the best performance and optimum safety. It has 2 expandable slots that can attach various uplink modules and 24 10/100Base-TX ports supporting PoE function.
