Features

Details about the features of the Digital 2x1x16 KVM Switch are as follows.

Target systems:

The Digital 2x1x16 KVM Switch has 16 target system ports. Up to 16 servers can be connected to the KVM switch from these ports using standard CAT-5 cables with RJ45 connectors. At each target server end, conversion cables are used to convert the RJ45 connector to VGA and USB connectors:

  • Single-USB Conversion Cable for Digital KVM provides a VGA connector and one USB connector. This cable provides video, keyboard and mouse signals and is used when you do not wish to implement tiering.
  • Dual-USB Conversion Cable for Digital KVM provides a VGA connector and two USB connectors. This conversion cable is required if you wish to implement tiering.

Tip: Both conversion cables support virtual media.

These conversion cables are shown in Figure 2.

Up to 16 servers can be directly connected to the KVM switch. You can increase the number of connected target systems by using a two-tiered arrangement of switches (as described in the ). Tiering allows up to 256 target servers to be accessible from one Digital 2x1x16 KVM Switch.

Local user connection:

The Digital 2x1x16 KVM Switch supports connectivity using the DVI and USB ports on the rear of the KVM switch. If a monitor with a VGA cable is used, you can optionally use the VGA to DVI Conversion Cable, 4X97A11108, which converts the DVI connection to a VGA connection. The keyboard and mouse are connected using two of the USB ports at the rear of the KVM switch.

Two additional USB 2.0 ports (1 rear, 1 front) are provided for the attachment of devices such as optical drives or memory keys. These devices can be made available on remote target systems as virtual media. Note, however, that the of virtual media is not supported with tiering.

The KVM switch provides an options menu where you can swtich between target systems and perform other management functions. Access to the menu is by pressing Scroll Lock twice. Additional hot keys provide additional functions as described in the user's guide.

Remote access over Ethernet:

Remote access to console switch and to the target systems is via a Web browser (default IP address is 192.168.0.192). The switch provides agentless remote control and access. No special software or drivers are required on the attached servers or client. Access is normally via a standard Ethernet network, requiring that the console switch be connected to the network via one or both Ethernet ports. Connecting both ports provides redundancy.

Local and remote user interfaces:

The mangement interface for the Digital 2x1x16 KVM Switch is browser-based, and is accessible both locally and remotely. You can use the local management interface by connecting directly to the local port and pressing Scroll Lock twice. You can also use the remote browser interface to manage your switch. The browser interface is launched directly from the switch, and any devices connected to the switch are automatically detected. The local and remote user interfaces share a similar look and feel.

Virtual Media:

The Digital 2x1x16 KVM Switch supports virtual media. Any devices connected to the USB ports on the KVM switch (for a local console sesssion) or connected to the remove user workstation (for remove console sessions) can be made available to the target server. With this feature, you can install software; install, upgrade, or recover the operating system; update the BIOS code; or boot the target system from a USB drive. Virtual media sessions are secured using 128 or 256 bit AES encryption.

The following virtual media types are supported for Windows and Linux systems:

  • Internal and external hard drives
  • Internal and USB-mounted CD and DVD drives
  • USB mass storage devices
  • PC hard drives
  • ISO images (disk images)
  • Digital audio devices

Use of external authentication servers and smart cards to authenticate access:

The Digital 2x1x16 KVM Switch supports Lightweight Directory Access Protocol (LDAP), Active Directory, and RADIUS for integration with existing authentication/security models. This ensures that you maintain only one set of user credentials and can maintain strict password rules.

The switch also allows 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 Dual-USB Conversion Cable, part number 4X97A11107.

Use of encryption:

The Digital 2x1x16 KVM Switch has an embedded FIPS 140-2 validated cryptographic module to provide 256-bit AES encryption of KVM session traffic, including video, keyboard, mouse, virtual media and smart card data.

Tiered consoles:

A single Digital 2x1x16 KVM Switch can directly connect to up to 16 target servers. The switch also supports a two-tier or cascaded configuration where one top-level switch can connect to 16 other second-level switches. Such a configuration allows up to 256 target servers to be managed from the single top-level switch.

The use of tiering requires Dual-USB Conversion Cables on the target systems.

To form this configuration, the 16 servers ports on the top-level switch are connected to RJ45 ports labeled "Tier" on each of the second-level switches (see the Connections section for the location of this port on the rear of the switch).

Note: Virtual media, smart card and audio are not supported with tiering.
