Emerson ATCA-S201 manual Understand Hot Swap, Connector Mechanical keying, Verify Slot Usage

ATCA‐S201 Installation

the chassis or board faceplates must be filled with an appropriate card or covered with a filler panel. If the EMI barrier is open, devices may cause or be susceptible to excessive interference.

2.5.2Understand Hot Swap

The ATCA module is electrically designed for hot swap within a fully powered chassis. To facilitate hot swap, there is a blue LED on the front faceplate. This LED is under software control of the IPMC managers.

The manager will illuminate the blue hot swap LED on the front faceplate when software has stopped and it is safe to remove the advanced rear transition module. If the blue-LED is not illuminated or blinking, it is not ready for removal. Powering down or removing a board before the operating system or other software running on the board has been properly shut down may cause corruption of data or file systems.

2.6Connector Mechanical keying

The ATCA supports mechanical connector keying to help prevent installation with incompatible components and RTM. The ATCA carrier board utilizes an A1/K1 key that is set at for universal)

2.7Verify Slot Usage

Prevent possible damage to module components by verifying the proper slot usage for your configuration.

In most cases, electronic keying (E-keying) will prevent power on of a board into an incompatible slot. However, as an extra precaution, you should be familiar with the slot purpose.

2.8Installing the ATCA carrier blade

This section describes a recommended procedure for installing the ATCA carrier module in a chassis.

Before you install your module, please read all cautions, warnings, and instructions presented in this section.

Handling modules and peripherals can result in static damage. Use a grounded wrist strap, static-dissipating work surface, and antistatic containers when handling and storing components.

Insert the board by holding the Module Handles–do not exert unnecessary pressure on the faceplate.

Hot swap compliant modules may be installed while the system is powered on. If a module is not hot swap compliant, you should remove power to the slot or system before installing the module.

1.Verify that you have taken the necessary antistatic precautions.
