Lenovo LCM8, LCM16 Product Manual
LCM8 and LCM16 Local Console Managers
Product Guide
The 1x8 and 2x16 Local Console Managers (LCM8 and LCM16) are the next generation analog keyboardvideo-mouse (KVM) console managers that provide enhanced local access, management, and security
capabilities to Lenovo server environments.
The LCM8 has eight target ports and supports one local user, and the LCM16 has 16 target ports and
supports up to two local users. Local video resolution can be up to 1600x1200 or 1680x1050 (widescreen).
Two level tiering allows you to manage up to 256 servers connected to multiple switches from one local
console. The following figure shows the LCM8 and LCM16.

Did you know?
The LCM8 and LCM16 support Two Factor Authentication (TFA), a system where two different security
elements are used in conjunction to authenticate to a server or desktop. TFA is an authentication process
where a person proves their identity with two methods: something you know (for example, a password or
PIN) and something you have (such as a smart card). Use of TFA is growing due to requirements by
governments and other institutions with a high need for security. An example of a TFA device that the
Local Console Managers support is the CCID-compliant Common Access Card (CAC) reader.
You can use the LCM8 and LCM16 with a Global Console Manager to provide network-wide remote
access with out-of-band access to servers, network equipment, and other devices with serial configuration
or console ports all from a single appliance. This unified approach improves staff efficiency by reducing
the time required to remotely diagnose, reconfigure, repair, or restore servers and network devices and
other hardware with serial configuration, management consoles, or both.

Installation instructions
The Local Console Managers enable you to share one workspace (keyboard, mouse, and display) across
many target systems. The target systems are connected to the console switch via CAT-5 cables and the
appropriate conversion option at the target end. Conversion options are available with either USB or PS/2
connectors.

With server densities continually increasing, cable bulk remains a major concern for network
administrators. The LCM8 and LCM16 switches significantly reduce KVM cable volume in the rack by
utilizing the innovative conversion option cables and single, industry-standard CAT-5 UTP cabling. This
allows a higher server density while providing greater airflow and cooling capacity. In addition, multiple
target systems can be daisy-chained together using CAT-5 cables, and then all connected to the console
switch using one cable, thereby eliminating a lot of cable clutter.
The 1754 LCM Digital Activation Key, part number 81Y2393, is a upgrade that turns the LCM KVM analog
switch into a digital device enabling remote access to servers it is connected to. This device enables one
remote user. The Digital Activation Key is a small USB device that is inserted into one of the USB ports at
the rear of the unit. The following figure shows the Digital Activation Key. An LED on the end of the key
shows its status.

Connections
The following figure shows the connections on the LCM16 Local Console Manager. The LCM8 Local
Console Manager has identical connections except it only has one local user port and eight analog rack
interface (ARI) ports, whereas the LCM16 has two local user ports and 16 ARI ports.

Note: The above figure shows the rear of the unit. There are no connectors on the front of the unit.
Features
Details about the features of the LCM8 and LCM16 are discussed in this section.
Local users
The LCM8 console switch enables one local user and the LCM16 console switch enables two local users
to access any attached servers. Local displays are connected to the console switch using VGA analog
connections and local keyboards and mice use USB connections.
Two additional USB ports (for a total of four USB ports) are available for each local user, and devices
plugged into these ports (for example, memory key, optical drive, and CAC reader) are visible to the target
servers if a Virtual Media Conversion Option Gen2 (VCO2), part number 46M5383 is used. Note, however,
that the VCO2 does not support chaining of target systems. (There is more information about virtual media
in the "Virtual media" section below.)
For the LCM16, if the target server is currently in use, a second user attempting to gain access will be
given an opportunity to force a connection to the device if their preemption level is equal to or higher than
the current user’s level. If the user attempting to gain access has a lower preemption level, the active user
will be asked if they wish to give up control to the new user (a timeout is also configurable).
