What is a Managed Industrial Switch
Atop’s EH (

igabit) are product lines of
powerful managed industrial switch which are referred to as OSI Layer 2* bridging devices. Unlike an
“
unmanaged
” switch, which is normally found in homes or in SOHO environments and runs in “auto-
negotiation” mode, each port on a “
managed switch
” can be configured for its link bandwidth, priority,
security, and duplex settings. The managed switches can be managed by SNMP software, web
browsers, Telnet, or serial console. Since every single port can be configured to specific settings,
network administrators can better control the network and maximize network functionality.
Atop’s managed switch is an industrial switch (as opposed to a commercial switch); a commercial
switch simply works in a comfortable office environment. However, an industrial switch is designed to
perform in harsh industrial environments, i.e., extreme temperature, high humidity, dusty air, potential
high impact or the presence of potentially high static charges. Atop’s managed switch works fine even
in these environments.
The managed switch is designed to provide faster, secure, and more stable network. One advantage
that makes it a powerful switch is that it supports technologies such as ERPS, iA-Ring, RSTP, MSTP,
and MRP. These technologies provide better network reliability and decrease recovery time down to
less than 20 ms.
The managed switch supports a wide range of IEEE standard protocols. This switch is excellent for
keeping systems running smoothly, reliable for preventing system damage or losses, and friendly to
all levels of users. The goal of this innovative product is to bring users a brand new network-
management experience.
