Local and remote user interfaces:
The OSCAR interface of older console switches has been replaced by a Web browser interface, which is
accessible both locally and remotely. You can use the local management interface by connecting directly
to the local port to manage the GCM16 and GCM32 switches. 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 GCM16 and GCM32 switches are automatically detected. The local and remote
user interfaces share a similar look and feel.
Virtual Media:
The GCM16 and GCM32 support virtual media when the target systems are connected using the Virtual
Media Conversion Option Gen2 (VCO2), part number 46M5383. You can use virtual media support to
connect USB 2.0 media devices to the console switch using one of the four USB ports and make those
devices available to any connected system. 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.
Control of how the USB device is connected to the target system is managed through the user interface.
The browser interface presents the following configuration options:
Virtual Media Locked: The locking option specifies whether a virtual media session is locked to the
KVM session on the target device. When locking is enabled (default) and the KVM session is
closed, the virtual media session will also be closed. When locking is disabled and the KVM session
is closed, the virtual media session will remain active.
Allow Reserved Sessions: Ensures that a virtual media connection can only be accessed with your
username and that no other user can create a KVM connection to that target device. When the
associated KVM session is disconnected, the virtual media session may be disconnected according
to the Locked setting.
Write Access: With this option, you can specify whether the target system can write to the USB
device (assuming it is writable).
Encryption: You can configure encryption levels for virtual media sessions. The choices are: None
(default), 128-bit SSL (ARCFOUR), DES, 3DES, and AES.
Note that USB ports are assigned to a single virtual media session and cannot be independently mapped.
This means you cannot map one USB device to one target system and another USB device to another
target system.
Use of LDAP and smart cards to authenticate access:
The GCM16 and GCM32 support Lightweight Directory Access Protocol (LDAP) for integration with
existing authentication/security models. This ensures that you maintain only one set of user credentials
and can maintain strict password rules.
