SecureLinx SLK Remote KVM User Guide 2-1
2: Introduction
This chapter provides introductory information about your SecureLinx SLK Remote
KVM. Topics in this chapter include:
Overview
SecureLinx is a family of remote server-management solutions that enable remote
clients to efficiently control their target servers and serial devices over a Local Area Net-
work (LAN) or the Internet using the standard Transmission Control Protocol/Internet
Protocol (TCP/IP). Secure remote access is provided through any web browser by
entering the SLK’s IP address. Once access is granted, remote clients can perform
activities such as resetting the target hardware, accessing the Basic Input Output Sys-
tem (BIOS), gaining keyboard and mouse control, and cycling power — as if they were
accessing the server locally.
Note: VNC can also be used for remote access. However, because VNC does not
support encryption, it does not provide a secure connection unless used with a Virtual
Private Network (VPN) or Secure Shell (SSH).
SecureLinx SLK Remote KVMs also provide automatic monitoring and notification
capabilities that notify you of problematic symptoms in your network environment before
they become critical. This break-through technology makes the SLK an essential com-
ponent of your server crisis-management infrastructure by giving you the power to
quickly recover from mission-critical server failures anywhere in the world.
SecureLinx SLK Remote KVMs also save you money by eliminating redundant periph-
erals (such as keyboards, monitors, and mice) and providing centralized control of mul-
tiple servers. Best of all, SecureLinx SLK Remote KVMs are plug-and-play solutions
that require no additional hardware or software, making initial setup quick and simple.
This non-intrusive approach means the SLK does not consume valuable server
resources while, at the same time, minimizes potential points of failure.

Introduction
2-2 SecureLinx SLK Remote KVM
With a small investment, SecureLinx SLK Remote KVMs can preserve precious office
space, centralize the management of your servers and serial devices, slash redundant
peripheral costs, and increase uptime and productivity.
SecureLinx SLK Models
SecureLinx SLK Remote KVMs come in three models:
❖SLK1 lets local and remote users control 1 server.
❖SLK8 lets local and remote users control up to 8 servers.
❖SLK16 lets local and remote users control up to 16 servers.
SLK1
The SLK1 provides one local user and multiple remote users with “shared” access to
one server. All users have simultaneous access to the single server. Because this
access is shared, only one user should control the server at a time. The SLK1 has two
serial ports.
SLK8
The SLK8 provides one local user and multiple remote users with access to up to eight
servers. The SLK8 supports independent operation between the local user and remote
users. This allows the local user to perform tasks independently of remote users. For
example, the local user might access the server on channel 1, while remote users
access the server on channel 2 at the same time.
By contrast, all remote users are dependent on each other. If a remote user changes
the view from the server on channel 2 to the server on channel 3, for example, all other
remote users view the channel 3 server.
The SLK8 has two serial ports.
SLK16
The SLK16 provides one local user and multiple remote users with access to up to 16
servers. The SLK16 supports up to 6 independent remote sessions. This allows the
local user and up to six remote users to perform simultaneous tasks independently of
each other. They can all access the same server or servers on different channels.
The SLK16 also allows a remote user to “lock down” his server channel for his use only.
Locking down a channel privatizes the session, preventing the channel from being
accessed by other users. When a channel is locked, only the user who locked it and the
SLK administrator can unlock the channel.
The SLK16 has three serial ports.
