The rails are shipped in the accessory kit with each chassis, and each rail kit will contain a left and right side
as a matched pair. Both sides must be installed in the rack to securely support the chassis.
If you ordered multiple UCS X9508 chassis, you might receive both types of rail kit. For example, in a shipment
of 4 chassis, the shipment might have all one type of rail kit, or a few chassis with each type of rail kit.
Compare the two types of rail kits:
Figure 13: Two Types of Rail Kits
The rail kits are similar in size, function, and construction with a few exceptions:
• the type of release tab at the top corner of the rail
• the type of locator pegs, either round or square, which temporarily hold the rail in the rack to allow free
use of both hands.
