Two hours of backup power must be provided for LAN Infrastructure, WAN boundary, VVoIP infrastructure, and VVoIP endpoints to support Immediate or Priority precedence C2 users.
Medium Severity
<VulnDiscussion>Unified Capabilities (UC) users require different levels of capability depending upon command and control (C2) needs. Special-C2 decision makers requiring Flash or Flash Override precedence must have eight hours of continuous backup power at all times. C2 users requiring Immediate or Priority precedence must have two hours of continuous backup power. Interrupting any of the routing or switching infrastructures will disrupt VVoIP service. If the infrastructure is interrupted, command and control communications are disrupted, preventing critical communications from occurring. When implementing a VVoIP system without considering uninterruptible power supply (UPS) needs for the VVoIP controllers and endpoints as well as the entire LAN, and supporting those needs with UPS systems, communications availability is reduced. All elements of the LAN infrastructure, WAN boundary, VVoIP infrastructure, and VVoIP endpoints directly supporting users with precedence needs must be provided with sufficient backup power to meet availability requirements. This reduction in availability threatens facility and personal security and safety as well as life safety during a power failure.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
