Mechanical safety

Drilling holes

CAUTION:
Do not drill holes in the cabinet yourself. Incorrect drilling operations can affect EMI shielding
performance of the cabinet and damage cables inside the cabinet. Metal shavings or debris from
drilling can cause a short circuit on the circuit boards.
•
Remove all cables inside the cabinet before you drill holes in the cabinet.
•
Wear goggles and protective gloves when drilling holes.
•
Prevent metal shavings from entering the cabinet when you drill holes. Clean up metal shavings,
if any after drilling holes in the cabinet.

Sharp objects

Wear protective gloves when you move the device to protect yourself from cuts.

Fan trays

•
To prevent damage to fan trays or the device, place the component, screws, and tools in a safe
place when you replace a component.
•
To avoid hurting your fingers or damaging the device, keep your fingers and the component
away from the spinning fan blades when you replace a component around a fan tray.

Moving heavy objects

WARNING!
• To avoid bodily injury, be cautious when you move heavy objects.
• To avoid bodily injury, pay attention to the unstable or heavy devices in the cabinet when pulling a
chassis out of the cabinet.
• The handles on a device with a no handling label attached are used only for adjusting the location
of the device. To lift the chassis, use tools.
When moving heavy objects, wear protective gloves to protect against sharp edges and follow these
guidelines:
•
Power off the device, remove all cards from the device, and remove all the external cables
(including power cables) before moving the chassis.
•
Moving the chassis requires a minimum of four people. As a best practice, use a mechanical lift.
•
Lift and put down the chassis slowly and never move suddenly.
