This flexible modular switch improves
today the bandwidth of your IEEE802.3/
u/x/z Gigabit and Fast Ethernet Network.
Tomorrow it it easily upgraded to your
future needs without high investment .
The switch offers 3 slots for hot-
swappable modules with 8 Fast Ethernet
ports each and 2 shared Gigabit ports
(SFP + 1000BaseTX). The 8-Port Fast
Ethernet modules are available for cop-
per, fibre and long distance attachments.
They can be easily changed without
influencing the switching activities on
the reminaing ports. The SFP slot can be
accomodated with any of our MiniGBICs
for additional: copper, multimode, single-
mode or WDM fibre ports, as well as
long distance fibre backbone attach-
ments.
You can access the switch through
an Ethernet port and a web-management
unit to monitor, configure and control
each port's activity.
In addition the switch provides a
broad set of useful features including
802.1p Quality of Service supporting
even sensitve real-time applications like
VoIP.
Port Mirroring mechanism copies
traffic from a specific port to a target port
in order to track network errors or ab-
normal packet transmissions without
influencing the data flow.
If you need to increase the bandwidth
between the switches, you can trunk
together up to 2 Fast Ethernet and 1
Gigabit Ethernet group (with a maximum
of 4 members each) providing very high
full duplex speeds. If any port within a
trunk fails, the packets are automatically
routed to the remaining active ports.
VLAN, including the advanved
802.1Q-in1Q function, enables you to
isolate traffic between different network
users. So you can increase your network
security and enhance the performance at
the same time.
In mission critial environments you
can configure a second switch with a
redundant back-up path to guarantee
transmission and reception of packets in
case of any fail-over within the network.
Finally the state-of-the art 802.1x
Access Control provides utmost security
for your network. You can limit user- or
machine-identities for each port and in
addition control the number of access
stations.
On the whole this switch is a very fle-
xible and cost-effective solution suitable-
for metro LAN and WAN applications.
