EISB Series
A Line of Managed and Unmanaged Ethernet Switching Hubs
INSTALLATION GUIDE
INTRODUCTION
The EISB Series of Ethernet switches give the user a choice between a simple,
easy-to-install Plug and Play device or a sophisticated instrument with several
advanced features for the discriminating network professional. Each of the 24
models in the series operates in extreme temperatures while offering a choice
of mounting, port count, media support and method of powering.
To optimize speed and throughput, some functions
are
automatically negotiated
:
Each twisted-pair port has Auto-MDIX and automatically optimizes its data
rate to 10 Mbps or 100 Mbps. The data rate of fiber ports is fixed at 100 Mbps.
Each port negotiates flow control—supporting the PAUSE function for full-
duplex segments and the backpressure scheme for half-duplex segments.
All units offer
non-blocking wire-speed operation
with a maximum data rate
of 148,810 frames per second for 100 Mbps Ethernet on all ports at full duplex.
Copper ports are wired MDI-X (internal crossover) for attaching NICs via
straight-through cables. Non-fiber models also have an uplink port (1X) wired so
only a straight-through cable is needed for cascading switches.
All devices operate from wide-range, low-voltage AC or DC sources — and
redundant power connections are available for backup considerations. They
come with the ability for either DIN-rail or panel mounting. The front panel
features bicolor LEDs for power; link status, activity, and data rate of each
port. Managed models include bicolor Status LEDs.
For managed switch features, consult the Software Manual.
