GCM16 and GCM32 Global Console Managers
Product Guide
The Global 2X2X16 Console Manager (GCM16) and Global 4X2X32 Console Manager (GCM32) are the
next generation digital keyboard-video-mouse (KVM) console managers that provide KVM-over-IP and
serial console management technology in a single appliance. Either console lets you access and manage
all servers remotely, even to the system BIOS, using your existing IP infrastructure.
The GCM16 has 16 target ports and supports up to 2 local users and 2 remote users, and the GCM32 has
32 target ports and supports up to 2 local users and 4 remote users. Figure 1 shows these two models.

Did you know?
The GCM16 and GCM32 Global Console Managers provide enhanced remote management, access, and
security capabilities 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 as well as
network devices and other hardware with serial configuration or management consoles, or both.
The serial capabilities of these appliances enable connecting and managing nearly any device with a serial
port directly from the console manager, including switches, routers, and PDUs. SSH and Telnet
connections are supported.

Page 2: Part Number Information
With server densities continually increasing, cable bulk remains a major concern for network administrators. The GCM16 and GCM32 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. -

Feature comparison The GCM16 and GCM32 replace the GCM2 Global Console Manager. Table 2 compares the console switches. Table 2. Comparison of features Feature GCM16 GCM32 Model 1754D1X 1754D2X Number of local concurrent users Number of remote concurrent users Local user connections - KVM... - Page 4 Number of local concurrent users: The GCM16 and GCM32 console switches enable one or two local user to access any attached servers. If the target device is currently in use, the 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.
- Page 5 Target systems: The GCM16 has 16 target system ports (known as analog rack interface or ARI ports) and the GCM32 has 32 target system ports. These can be directly attached to systems with the appropriate USB or PS/2 conversion option connector on the end.

- Page 7 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.
- Page 8 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.
