®
issues facing IT administrators today. The Avocent family of DSR
cost-effective KVM over IP appliances specifically designed for IT administrators who
need to easily troubleshoot, reboot or even power cycle servers or serial-based network
devices in branch offices. Using standard IP connections, our patented KVM over IP
technology provides a single, centralized management interface to access and control
devices regardless of location or type. The DSR branch switches, built on field-proven
KVM over IP technology, combine external modem support and power control in a single
solution. This complete solution provides secure 24/7 remote access to critical network
devices in your branch offices. With remote access to diverse devices and a secure,

Network Operations
Center (NOC)
With the family of DSR branch switches,
administrators in the NOC can troubleshoot
their remote servers or serial devices without
ever leaving their desk. DSView® management
software lets administrators manage remote
servers and VT100 network devices in branch
offices with the same DSView interface they
use to manage their data center devices.

Q: I have servers at multiple sites. How do I use the Avocent
DSR branch switches to provide access?
A: The DSR branch switches can be deployed wherever
computers or servers are located. They connect to your
network. Your technicians and administrators can access the
attached devices directly from their desk.
Q: How does this branch office solution work with the
®
DSView
software I have in my data center?
A: The DSR branch switches are part of the Avocent DS Series
KVM over IP switching solution. The DSR branch switches
are accessed using Avocent DSView management software.
Users do not have to learn a new interface since they would
use the same DSView software to access a server in the
data center or in a remote office.
Q: Can the DSR branch switches provide access to
other devices?
A: The DS Series has a wide variety of connection adaptors.
Use the VT100 serial adaptor to access routers, DSUs or
other networking devices.
Q: How do I get access if my network connection to a site
is down?
A: The DSR branch switches have a port that can be connected
to a modem. This provides access to the site when the
IP connection is not working. By connecting the router or
DSU to the DSR branch switch, you can diagnose WAN
or server problems.
Q: I use remote control software to manage my remote
locations. How is this different?
A: The DSR branch switches connect to the keyboard, video
and mouse port of the computer. Unlike remote control
software, the DS Series products do not require a functioning
operating system, network stack, or application to be running
to access the computer. By connecting externally, a CTRLALT-DEL command can be sent to reboot the computer. During
the boot up, the BIOS can be accessed or the boot can be
single stepped in order to troubleshoot boot problems. Remote
control software cannot give boot level access.
Q: Depending on my site, my link speeds can be different.
How do the DSR switches handle different speeds?
A: The DSR branch switches use the Avocent Dambrackas Video
TM
Compression
(DVC) algorithm. It provides selections to
reduce the number of colors, including a gray scale selection,
to operate over a variety of link speeds including speeds of
an analog modem.
Q: What are the differences between the branch switches?
A:
SWITCH TARGET DEVICE USERS
DSR1021 8 1 local/1digital
DSR1022 4 1 local/1digital
DSR1024 1 1 local/1digital
Q: Sometimes I need to cycle power to a device to reset it.
How do I cycle power remotely?
A: The DSR branch switches have a power control port built into
the appliance. By connecting this port to an Avocent SPC
power control device, you can remotely check power starts
and cycle power. This means no more calling someone at the
location to explain which power switch they need to cycle.
