CAUTION: Never place your hand inside an empty card or module bay. You should never have cause to place a hand anywhere inside the Topspin chassis. Unused card and module bays should always have a Topspin cover over the bay to ensure proper safety, ventilation, and cooling.

General Cautions

CAUTION: No user is authorized to remove the Topspin system enclosure cover. The internal chassis contains no user-serviceable components. Removing the enclosure cover voids your warranty. See the warranty card for further details regarding the servicing of your chassis.

CAUTION: Opening and/or modifying expansion and system modules may void your warranty. Refer to your warranty to determine access restrictions.

In general:

•Do not spill food or liquids on your system components.

•Protect your Topspin system from sudden power-surges and interruptions by using a surge suppressor, line conditioner, or uninterruptable power supply (UPS).

•Place cables appropriately so that they do not obstruct any egress within the data center and they do not block any ventilation inlets or outlets.

•Rack mount the Topspin chassis according to the rack manufacturer recommendations.

Laser Cautions

CAUTION: Only qualified service technicians should repair laser devices.

CAUTION: Only open, modify, or service laser devices as specified in the manufacturer documentation.
