Application Overview

Power utilities commonly utilize Gigabit-speed Ethernet systems in substations for automatic control, protection, remote maintenance and disturbance analysis. These systems are mission critical requiring ruggedized, redundant networks to ensure maximum system reliability.

Key Considerations

Industrial grade switches for protection against ESD and certified with EMI/EMC protection with overvoltage and overcurrent protection.
Low maintenance costs (OPEX) with remote management functions.
Auto-provisioning to update the firmware for the entire network, rather than only a single switch.
Precise synchronization as per IEEE 1588v2 to simplify integration of all functions.
Extensive management and filter functions with a variety of redundancy protocols and port security.

Key Volktek Benefits

	Feature		Benefit
Reliability	Redundant Power	Remains On During Power Failure	1) Built-in surge protection, dual power sources, and battery backup 2) Ensure stable device operations for 24/7 network reliability.
Reliability	USB Port	Lower OPEX for Configuring and Upgrading	The USB flash drive port has multiple functions including - Upgrading undeployed switches - Easily access for installation and upgrades - System-config and local Syslog back-up
Availability	Link Redundancy	Fast Network Recovery	1) Rapidly react to physical link failure and recover immediately 2) Provide an alternate pathy link to support continuous transmission.
Performance	Quality of Service (QoS)	Define the Critical Networks	1) Specific networks can be prioritized 2) Optimize the network performance and bandwidth utilization
Security	802.1x RADIUS / TACACS+	Secure the Network by Authenticating the Users	1) Specify a whitelist of allowed MAC addresses, allowing only those devices to connect to the network. 2) Limits the number of devices connected to a single downlink port known as Dynamic Assignment.
Security	e-mail Alarm	Triggered Events Alert Via Email	1) Notify the administrator if real-time problems occur such as firmware or configuration changes, device status, link connectivity status, etc. 2) Help administrators to quickly identify, isolate and resolve network issues.
Management	Link Layer Discovery Protocol (LLDP)	Access Device and Network Information	Alert messages sent from a remote SNMP-enabled device to a center SNMP server.
