NEBS Level 3 Compliance for the DC-Powered Server

Telcordia certified that the DC-powered version of the Netra 240 server meets
NEBS Level 3 requirements per SR-3580, including the appropriate sections of
GR-63-CORE (Network Equipment-Building System Requirements: Physical Protection) and GR-1089-CORE (Electromagnetic Compatibility and Electrical Safety - Generic Criteria for Network Telecommunications Equipment).
