forwarded to its destination) of the ITS
Blade
Ethernet Switch varies with the port-speed types,
and the length of the frame is a variable here, as it is with all store-and-forward switches. For 10
Mb-to-10 Mb or 10 Mb-to-100Mb or 100Mb-to-10 Mb forwarding, the latency is 15
microseconds plus the packet time at 10Mb. For 100Mb-to-100Mb forwarding, the latency is 5
microseconds plus the packet time at 100Mb.

Features and Benefits
100Mb switching services for high performance Ethernet LANs
Magnum ITS
Blade
provides Fast Ethernet switching on all ports. They perform
high-speed filter/forward operations on the traffic, giving each port’s segment a
full 100Mb (or possibly 10 Mb for RJ-45 ports) of bandwidth.
IEEE 802.1P QoS prioritization supports data and streaming traffic
Mixtures of bursty data packets and streaming packets for video are supported,
with priority use of the bandwidth given to streaming for best quality video.
Two “future-proof” fiber ports with SC connectors
Built-in fiber ports may be ordered with 100Mb full-duplex multi-mode SC,
single-mode SC, and (special order) SSCL-type connectors. The fiber ports are
set to full-duplex mode. No Media Converters needed.
All RJ-45 ports are auto-negotiating, and auto-crossover
RJ-45 ports support twisted pair “copper” segment connections, with 10 or
100Mb speed and full / half-duplex mode selected by Ethernet standard IEEE
802.3u auto-negotiation. Auto-crossover is standard.
Front-mounted LEDs for convenient viewing
The LEDs that indicate operating status are on the top of the unit for easy
viewing in any situation. As the units are vertically mounted in 2070 Box, Front-
surface viewing is convenient for the user to see the status.
Installation is “Plug and Play”, operation is transparent to software
The Magnum ITS
Blade
operates as a hardened switch, only forwarding those
packets from each domain that are needed on the other domains. Internal address
tables are self-learning, enabling users to change port connections or 10/100
domains without affecting operations.
Thermal design techniques for use in temp. uncontrolled applications
The ITS
Blade
’s advanced thermal techniques extend the ambient temperature
operating range beyond standard product ratings, and improve operating lifetime
and reliability.
