Hot-Swap T
rays
Hot-Swap Trays
Maximum uptime in a server requires devices that can be easily replaced or
“swapped.” The main hard disks are mounted in internal hot-swap trays for
easy replacement. To remove the tray, unlock the tray and pull on the handle.
A lock secures the handle and switches on or off the power to the hard drive.
Hot-Swap Tray Interface
The front of the hot-swap tray provides a keylock in order to switch the
power on, which also locks the handle, and switch the power off, which also
releases the handle. Two LEDs provide information on the power and activ-
ity status of the hard disk drive. When power is received by the hot-swap
tray’s connector board, the power LED will light. When data is written or
read to or from the contained hard disk drive, the activity LED will flash
proportional to the amount of data transferred.
