IS420ESWAH3A GE Mark VIe, IONet Ethernet Switch

Description:

The IS420ESWAH3A is an IONet Ethernet switch developed by GE for use with its Speedtronic Mark VIe gas turbine control systems. It features eight 10/100BASE-TX ports, Achilles-certified controllers, and Fieldbus technology to meet NERC version 5 Protection Reliability Standards for Critical Infrastructure. The switch has a conformal coating, making it suitable for hazardous environments, and can operate within temperatures ranging from -40 to 158 degrees Fahrenheit.

Key features include compatibility with 802.3, 802.3u, and 802.3x standards, full/half duplex auto-negotiation, a 100 Mbps FX uplink port, and HP-MDIX auto-sensing. It also supports flow control between switches using IEEE-defined pause packets. The IS420ESWAH3A boasts an impressive Mean Time Between Failure (MTBF) of over 4 million hours at 35°C (95 °F).

The switch can be panel or DIN-rail mounted, offering easy access to user connections and satisfying vibration and shock requirements. Its dimensions are 138 x 86 x 56 mm (5.45 x 3.40 x 2.20 in), and it supports two redundant diode-OR’d power supply inputs of 18 to 36 V dc. Convection cooling is provided regardless of the mounting orientation. The device is resistant to corrosion and meets IEC 60721-3-3 Class 3C2 grounding provisions.

With an operating temperature range of -30 to 65°C (-22 to 149 °F) and humidity levels between 5 to 95% (non-condensing), the IS420ESWAH3A ensures reliable performance. It also meets Universal Building Code (UBC) seismic vibration standards.

Diagnostic capabilities include LED indicators for link presence, activity, duplex, and port speed, with different colors signifying various statuses. The switch offers benefits such as longer part availability for future network expansion, backward compatibility with legacy systems, and improved performance for real-time control systems.

In terms of conformance criteria, the IS420ESWAH3A supports IEEE 1588 timing for synchronizing packet traffic within a 1-microsecond window, assessed across four specific scenarios involving multicast packet loads and IEEE 802.3x flow control negotiation.
