SEL-2730M Удирдлагатай 24 портын Ethernet шилжүүлэгч

The SEL-2730M is designed to operate in harsh environments, like those found in electric utility substations and industrial plants. The switch provides Ethernet connectivity for SCADA, engineering access, and control, and it offers the same reliability found in SEL protective relays. The SEL-2730M meets or exceeds IEEE 1613 (Class 1), IEC 61850-3, and IEC 60255 industry standards for vibration, electrical surges, fast transients, extreme temperatures, and electrostatic discharge.


Designed, built, and tested for trouble-free operation in extreme conditions, the SEL-2730M meets or exceeds IEEE 1613 (Class 1) and passed KEMA testing to validate compliance to IEC 61850-3 Class A standards for communications devices in electric power substations, with a specified temperature range of –40º to +85ºC (–40º to +185ºF).

SEL is committed to providing superior reliability and quality in all of its products. The SEL-2730M is equipped with hot-swappable, dual power supplies, allowing simultaneous connection to primary and backup power sources. This ensures no loss of service due to a single power source failure. The SEL-2730M also monitors ports for link flap, when an interface continuously alternates between up and down states, often due to a bad cable.

Easy to Use and Administer
The SEL-2730M is easy to install and configure. The web management interface has been engineered to emphasize ease of use for common tasks, such as setting up priority communications using VLANs. Any selection of ports can be mirrored for integration with an Intrusion Detection System (IDS). Settings can be configured online through the secure web interface or offline for later uploading to the switch. Access to the HTTPS web interface can be managed centrally via LDAP or RADIUS.

Flexible, Modular Design
The base-model SEL-2730M has 4 Gigabit Ethernet copper ports and 16 10/100 Mbps copper Ethernet ports, built as 4-port modules. These modules can be ordered as 4 single-mode fiber-optic ports, 4 multimode fiber-optic ports, or 2 copper and 2 multimode fiber-optic ports (Ports 17–20 only). In addition, up to 4 fiber-optic or copper Gigabit Ethernet ports can be added via SFP transceivers for a total of 24 ports.

Comprehensive security features, such as SNMPv3, HTTPS, and MAC security, ensure that only authorized users and devices have access to the network.

BPDU Guard prevents spurious BPDU packets from affecting the network. Port rate limiting helps prevent broadcast, multicast, or unicast Ethernet storms from disrupting network operations.

SEL builds all of its switches in U.S.-based manufacturing facilities using the same processes used to build its relays, and offer the same no-questions-asked, worldwide, ten-year product warranty for our networking equipment that they do for protection and automation equipment.
