Product Overview |
|
The EISB_M B-Line Series of compact managed switching hubs provide
management functionality in situations where an extended temperature
range of
–40° to +75°C are expected — enabling them to
perform successfully in outdoor applications.
Within a constant form factor (panel space consumed) requiring only
1.75" of DIN-rail, these switches can support 8, 16 or 24 ports
with copper and fiber/copper combinations in a rugged aluminum enclosure.
Equipped with the conventional features standard in Plug and Play
switches, the EISB_M B-Line Series is also designed with management
features including RapidRing®, VLAN, trunking, (QoS) (Quality
of Service), and SNMP (Simple
Network Management Protocol).
The switch learns port assignments by reading Ethernet frames and
logs source addresses into a table which can hold more than 4,000
addresses in the 8-port unit, over 8,000 in the 16-port unit and
more than 12,000 in the 24-port unit. With this information, it
improves throughput by restricting traffic to only those ports party
to a data exchange — while other data is simultaneously exchanged
on other ports. Store-and-forward operation of frames is implemented
using 256 kB of built-in memory in the 8-port unit, 512 kB of built-in
memory in the 16-port unit and 768 kB of built-in memory in the
24-port unit.
Only standard straight-through cables are needed to connect the
copper ports to stations or another hub since the copper ports are
Auto-MDIX compliant — meaning any port can function as an uplink
port to another switch or end-station. In addition to one power
LED, each port has an LED showing link/activity/data rate by color:
green for 100 Mbps, yellow for 10 Mbps. Flashing indicates port
activity.
The EISB is shipped with a DIN-rail clip installed. If direct mounting
to a sub-panel is desired, the DIN-rail clip can be removed and
the attached mounting ears extended to provide panel mounting.
The unit can be powered from either wide-range, low-powered AC or
DC power sources. Redundant power connections are provided to accommodate
back-up schemes.
