GE ESWx Industrial Ethernet Switch
GE ESWx Industrial Ethernet Switch
DESCRIPTION
GE’s Industrial Ethernet 10/100 switches (ESWx) provide the performance and features needed in today’s real-time industrial power plant control systems.
Product Features
• 802.3, 802.3u, and 802.3x compatibility
• 10/100 base copper with auto negotiation
• Full/half duplex auto-negotiation
• 100 Mbps FX uplink port
• HP-MDIX auto sensing
• LEDs for Link Presence, Activity and Duplex, and Speed per port (each LED has two colors)
• LED for Power
• Minimum 256 KB buffer with 4K media access control (MAC) addresses
Flow Control (Pause)
The switch supports flow control between switches. It uses IEEE® defined pause packets to receive and honor pause packets. The switch only sends the pause packets if it needs flow control on a port.
Diagnostics
Link Presence, Activity and Duplex, and Speed per port LEDs each have two colors to indicate status.
• LED one
− Flashes Green for activity at Full Duplex
− Flashes Yellow for activity at Half Duplex
• LED two
− Green = Link and 100 Mb
− Yellow = Link and 10 Mb
− No led lit = no link
Conformance Criteria
The packet traffic can be synchronized by IEEE 1588 timing and triggered to initiate within a 1-microsecond packet start window. The switch’s capability and conformance is tested to meet the following four criteria:
• Initiation of the required Multicast packet load on one port, without IEEE 802.3x flow control negotiated
• Initiation of the required Multicast packet load on one port, with IEEE 802.3x flow control negotiated
• Initiation of the required Multicast packet load distributed across all ports, packet count per port must average required per number of switch ports with no IEEE 802.3x flow control
• Initiation of the required packet Multicast load distributed across all ports, packet count per port must average 200 per number of switch ports with IEEE 802.3x flow control negotiated on half the ports
Benefits
• Longevity of parts availability for future network expansion
• Backwards compatibility to legacy systems
• Higher performance for real-time control systems of today
• Higher performance for real-time control systems of today
