LCD Tray Console Flashcards
What is an LCD tray console?
- Is an integrated device that combines monitor, keyboard and mouse into one single unit that can be mounted in a server rack. To let you view, interact and control the connected devices, such as KVM and servers.
For KVM: It provides out-of-band access to KVM switches, allowing IT administration to manage multiple servers from a single location, even if the network is down.
How does it work?
- Slide the LCD tray console from the server rack.
- Flip up the LCD screen, then there’s a full keyboard and a touchpad.
- To display the output from the target devices, and put a command to it for you to control and navigate it.
- It will not function as expected if there are no connected devices.
Benefits
Space Saving: Fits into 1U rack space, conserving valuable server rack space.
Convenience: Eliminates the need for a separate crash cart, simplifying server management in crowded data centers.
Efficiency: Makes it easier to manage multiple servers from a single location without needing to physically move around the data center.
Included in the box
- Two outer rails
- Miscellaneous Hardware kit (user guide, safety sheet, cage nuts, clip nuts, screws and cable straps)
Installation process
- Preparation:
a. Ensure the server rack has sufficient space (1U) for the LCD tray console.
b. Gather necessary tools:
• Two outer rails (provided)
• Miscellaneous hardware kit (user guide, safety sheet, cage nuts, clip nuts, screws and cable straps) (provided)
• One No.2 Phillips screwdriver (not provided)
• One cage nut insertion tool or flat- blade screwdriver (for installing cage nuts in some racks) (not provided)
- Mounting Rails Installation:
a. Attach the mounting rails to the rack this usually involves screwing the rails into the rack pose.
b. ensure the rails are level and securely fastened.
- Console installation:
a. slide LCD tray console into the mounted rails.
b. secure the console in place by fastening the front panel screws to the rack.
- Connecting to a KVM switch:
a. Connect the console to a KVM switch using the provided cables. Typically this involves connecting video keyboard and mouse cables from the console to the kvm switch.
b. If the console has built in cables, plug them into the appropriate parts on the KVM switch.
- Power and USB connections:
a. Plug in the power adapter of the console and ensure its connected to a power source.
b. Connect any usb peripherals (such as external drives or additional input devices) to the usb ports on the console.
- Testing:
a. Power on the console and the connected KVM switch.
b. Verify that the console displays the output from the connected servers.
c. Test the keyboard and mouse functionality to ensure they are working correctly.

CMA (Cable management arm)
- it is an accessory used in server racks and data centers to manage and organize cables efficiently and to fully extend the console from the rack.
Attachment: The CMA is typically attached to the rear of the rack mounted equipment such as an LCD tray console or server.
Articulation: it is designed to move in tandem with the equipment as it slides in and out of the rack ensuring the cable stays organized and does not get pulled or strained.
