The Cisco® IPS 4240-DC is a purpose-built intrusion prevention sensor that augments Cisco's market-leading line of intrusion detection and prevention system appliances, delivering the industry's best price/performance marks while achieving high levels of reliability (Figure 1). The Cisco IPS 4240-DC is based on the IPS 4240 platform but introduces unique features, such as support for DC power and compliance with NEBS (Network Equipment Building Systems) Level 3 guidelines. This allows the IPS 4240-DC to be deployed in environments that have specific requirements pertaining to NEBS Level 3 compliance.
