The GCM16 and GCM32 switches also allow you to use smart cards to ensure access is authorized.
Smart cards are pocket-sized cards that store and process information. Smart cards such as the Common
Access Card (CAC) can be used to store identification and authentication to enable access to computers,
networks, and secure rooms or buildings. Smart card readers are connected directly to the switch via one
of the USB ports, or they can be connected to any remote workstation that is running the remote browser
interface or DSView management software and is connected to the switch using an Ethernet connection.
Note: For smart card use, the target device must be connected to the console switch using the Virtual
Media Conversion Option Gen2 (VCO2), part number 46M5383.
Use of encryption:
The GCM16 and GCM32 support encryption for KVM signals and for remote media. Available encryption
levels are 128-bit SSL, DES, 3DES, or AES. These are configurable via the browser interface.
True serial capabilities:
The GCM16 and GCM32 switches support Serial Conversion Option (SCO) cables that provide serial
capabilities through Telnet. The capability provides a proper serial connection, not serial-to-VGA
conversion. You can launch an SSH session or a serial client from the on-board Web interface to connect
the targets that are connected to the GCM16 and GCM32 switches with an SCO cable. The SCO includes
a separate USB-to-barrel power cord adapter - see Figure 2. Connect the USB end of the adapter to an
available USB port on the target system to supply power to the SCO.
Managing Intelligent Power Distribution Units
The dedicated Power Distribution Unit (PDU) ports on the GCM16 and GCM32 switches support the direct
attachment of certain Avocent-branded Intelligent PDUs and can provide the ability to view and manage
these units directly through the switch. Lenovo Intelligent PDUs are not supported.
