• Dell recommends that only individuals with rack-mounting experience install an SC460 expansion enclosure in a rack.
• When installing multiple expansion enclosures in a rack, ll the rack from the bottom up and empty the rack from the top down.
• The rack construction must support the total weight of the installed expansion enclosures. The design should incorporate stabilizing
features suitable to prevent the rack from tipping or being pushed over during installation or in normal use.
• To prevent the rack from tipping, slide only one expansion enclosure out of the rack at a time.
• Make sure that the expansion enclosure is always fully grounded to prevent damage from electrostatic discharge.
• When handling the expansion enclosure components, use an electrostatic wrist guard or a similar form of protection.

swappable. When disconnecting power, rst power down the storage system using the storage client and then unplug the power
