Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

Before you read this guide, review the Cisco IronPort Quickstart Guide and the latest product release 
notes for your appliance. In this guide, it is assumed that you have unpacked the appliance, physically 
installed it in a rack, and turned it on. 

If you have already cabled your appliance to your network, ensure that the default IP address for the 
Cisco IronPort appliance does not conflict with other IP addresses on your network. The IP address that 
is pre-configured on the Management port (on Cisco IronPort X1000/1000T/1050/1060/1070, 
C60/600/650/660/670, and C30/300/300D/350/350D/360/370 appliances) or the Data 1 port (on Cisco

protection until new signature updates are deployed.
