E5-APP-B card packages are designed to be integrated with features that run on a Signal Transfer Point (STP). E5-APP-B cards for these applications run in a Direct Current (DC) environment and are delivered as a pair to be installed in an EAGLE using heavy duty frames, along with breaker panels and Ethernet communication equipment.

For more information about EAGLE shelves, see the EAGLE Hardware Guide.

This chapter provides an overview of E5-APP-B cards and highlights E5-APP-B card features, components, and adapter interfaces.

An E5-APP-B card comes with two removable drive modules when first ordered. A complete shipping package for applications includes:

• Two E5-APP-B standard EAGLE double-wide cards, identified as A and B. Each E5-APP-B card is loaded at the factory with platform software and application software.

• Two removable drive modules for each separate card. For more information about these components, refer to the documentation delivered with the product.

Figure 3-1 shows an example E5-APP-B card in a shelf(1).

A single E5-APP-B card is a general-purpose application server (AS) that offers high transaction rates with low latency. It supports a variety of application solutions for the wireless and wireline telecommunications infrastructure to provide the building blocks for next-generation signaling systems.

The E5-APP-B card is a scalable computing platform constructed with state-of-the-art components packaged on a double-wide card designed to fit into two slots of an EAGLE shelf. Each E5-APP-B card has two removable drive modules. E5-APP-B cards are installed in pairs for redundancy and high availability.

Figure 3-2 shows a single E5-APP-B card. This view shows where hardware components, especially Field Replaceable Units (FRUs), are located.

Figure 3-2 E5-APP-B Card

The following are Field Replaceable Units:

• E5-APP-B card (1)
• Drive Module (4)

For more information about FRUs, see the corresponding Alarms and Maintenance guide included in this release.

E5-APP-B Card Status Indicators

Figure 3-3 E5-APP-B Card Indicators

The following light-emitting diode (LED) status indicators (see Figure 3-3) can be found on the E5-APP-B card:

• One Server Status indicator (A)
• Four E-Net link and Active LED status indicators (B)
• Two drive module status indicators (C)
• One Card Eject status indicator (D)

For more information about the diagnostics that manage these alarm and status indicators, see E5-APP-B Card Diagnostics.

The E5-APP-B card consists of the following standard hardware components:

• Dual Core 2.66GHz 64-bit processor

• Active/Trial BIOS architecture

• 1333 megahertz (MHz) processor front side bus speed

• 8 GB DDR2 DRAM

• Light Emitting Diode (LED) status display

• Hardware monitors that read and report:

  • Supply and core voltages

  • Fan alarm inputs

  • Ambient and processor temperatures

• Two drive modules (Field-replaceable Units (FRUs))

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

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

Device: /dev/sdX [SAT], SMART Failure: FAILURE PREDICTION THRESHOLD 
EXCEEDED: ascq=0xNN

The disk drives have high mean time between failures (MTBF) and can be easily replaced.

All components that comprise the E5-APP-B card platform are designed for testability to ensure that operational status can be accurately determined and that appropriate levels of fault detection and isolation are possible with a minimum of effort.

The following levels of diagnostics are provided:

1. Online diagnostics actively monitor the health of a running E5-APP-B card platform. When online diagnostics encounter a problem, an alarm is raised and front fascia light-emitting diodes (LEDs) are illuminated to indicate the status of certain components of the E5-APP-B card. For more information about the E5-APP-B card LEDs, see Table 3-3. Online diagnostics can be run while maintaining in-service operation of node.

Diagnostics enable troubleshooting of installed systems by verifying operational capability of Field Replaceable Units (FRU) and operational status of peripheral system components (such as cables and connectors) through automated testing initiated by FRU components. Examples are loop-back and link tests.
