Four 1 Gigabit (Gb) Ethernet ports
Electrical Features
The E5-APP-B card has the following standard electrical features:
• Operates from -40 VDC to -56.7 VDC power input, according to Network Equipment Building
System (NEBS) requirements in accordance with typical telecommunications applications
• Includes short-circuit protections and safety precautions in accordance with common standards
Mechanical Design and Maintenance Features
The E5-APP-B card mechanical design meets all applicable NEBS requirements and is designed to
protect all active components. The design has efficient component cooling using low-impedance air
paths, and its compact size allows multiple units to be configured in a shelf with zero clearance.
The E5-APP-B card has been designed for easy maintenance. The following components are
Field-replaceable Units (FRUs):
• The E5-APP-B card
• The drive module assembly
The disk drives have high mean time between failures (MTBF) and can be easily replaced.
Note: When removing or replacing FRUs, use the procedures in the corresponding Alarms and
Maintenance manual for this release. Use the inject/eject switch on the E5-APP-B card before switching
OFF all circuit breakers or power distribution units supplying redundant power. For more information
about troubleshooting systems and performing soft shutdowns, see the appropriate maintenance
manual for the application.
