• 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

LC-type connection
When used as a replacement switch, a port adapter (supplied
with the replacement kit) is used if needing to interface an
existing SC fiber termination to the LC fiber port.
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.
Reliability and Performance
Because high reliability is critical to any controls solutions
business, the switch exceeds 4 million hours Mean Time
Between Failures (MTBF) at 35°C (95 °F) ambient temperature,
ground fixed controlled environment. The switch also meets
the following performance criteria:
Performance Criteria
Item Description
Switch
latency
Switch packet latency does not exceed
required application limits.
Switch
architecture
The switch supports store and forward
architecture, providing high data confidence.
Inrush
current
The switch provides soft start capability that
limits inrush current to less than 200% of the
normal operating current.

Specifications
Item Description
Mounting The switch enclosure can be panel mounted
(switch mounts to rear wall of panel with
bracket) or DIN-rail mounted. DIN-rail
mounting meets vibration and shock
specifications. User connections are freely
accessible with both mounting types.

Humidity Operates in a 5 to 95% relative humidity
non-condensing environment without any
external temperature or humidity excursions

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
