Searies: PT-7828 Series
The PowerTrans PT-7828 switches are high performance Layer 3 Ethernet switches that support Layer 3 routing functionality to facilitate the deployment of applications across networks. The PT-7828 switches are also designed to meet the strict demands of power substation automation systems (IEC 61850-3, IEEE 1613), and railway applications (EN 50121-4). The PT-7828s Gigabit and Fast Ethernet backbone, redundant ring, and 24 VDC, 48 VDC, or 110/220 VDC/VAC dual isolated redundant power supplies increase the reliability of your communications and save on cabling and wiring costs. The modular design of the PT-7828 makes network planning easy, and allows greater flexibility by letting you install up to 4 Gigabit ports and 24 Fast Ethernet ports. Optional front or rear wiring makes the PT-7828 switches suitable for a variety of applications. This product supports expansion modules. Click here for info on available modules.
General Layer 3 switching functionality to divide a large network into hierarchical subnets and allow data and information to communicate across networks Command Line Interface (CLI) for quickly configuring major managed functions Software-based IEEE 1588v2 PTP (Precision Time Protocol) for precise time synchronization of networks DHCP Option 82 for IP address assignment with different policies EtherNet/IP and Modbus/TCP industrial Ethernet protocols supported Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250 switches), RSTP/STP, and MSTP for network redundancy Supports multicast routing protocols PIM-DM/DVMRP Supports advanced VLAN capability with Q-in-Q tagging IGMP snooping and GMRP for filtering multicast traffic from industrial Ethernet protocols IEEE 802.3ad, LACP for optimum bandwidth utilization Bandwidth management prevents unpredictable network status Multi-port mirroring for online debugging Automatic warning by exception through email, relay output RMON for efficient network monitoring and proactive capability Automatic recovery of connected devices IP addresses Line-swap fast recovery Configurable by Web browser, Telnet/Serial console, CLI Windows utility, and ABC-01 automatic backup configurator Cyber-security User passwords with multiple levels of security protect against unauthorized configuration SSH/HTTPS is used to encrypt passwords and data Lock switch ports with 802.1X port-based network access control so that only authorized clients can access the port Disable one or more ports to block network traffic 802.1Q VLAN allows you to logically partition traffic transmitted between selected switch ports Secure switch ports so that only specific devices and/or MAC addresses can access the ports Radius/TACACS+ allows you to manage passwords from a central location SNMPv3 provides encrypted authentication and access security
