Cisco Cisco Email Security Appliance C170 Guia Da Instalação

• System rack kits are intended to be installed in a rack by trained service technicians. If you 

install the kit in any other rack, be sure that the rack meets the specifications of a 
computer manufacturer rack.

• Before working on the rack, make sure that the stabilizers are secured to the rack, 

extended to the floor, and that the full weight of the rack rests on the floor. Install front and 
side stabilizers on a single rack or front stabilizers for joined multiple racks before working 
on the rack.

• Always load the rack from the bottom up, and load the heaviest item in the rack first.

• Make sure that the rack is level and stable before extending a component from the rack.

• Use caution when pressing the component rail release latches and sliding a component 

into or out of a rack; the slide rails can pinch your fingers.

• After a component is inserted into the rack, carefully extend the rail into a locking 

position, and then slide the component into the rack.

• Do not overload the AC supply branch circuit that provides power to the rack. The total 

rack load should not exceed 80 percent of the branch circuit rating.

• Ensure that proper airflow is provided to components in the rack.

• Do not step on or stand on any component when servicing other components in a rack.

• Do not plug a modem or telephone cable into the network interface controller (NIC) 

receptacle.

• Do not open any panels, operate controls, make adjustments, or perform procedures on a 

laser device other than those specified in the product's documentation.

• Only trained service technicians should repair laser devices.

Most IronPort products have no field-servicable components which require you to remove the 
system covers. Please contact IronPort Customer Support if you have questions about 
removing or replacing a component.

If IronPort Customer Support explicitly instructs you to remove the system covers, perform the 
following steps in the sequence indicated.
