In this section:
SBC 5400 Systems configured for AC power are equipped with either single or dual redundant AC power supplies. These are Customer Replaceable Units (CRU). The figure AC Power Supply depicts a dual redundant configuration. The AC Power Supply product code is SBC-5400-PSUAC-N.
In a dual redundant power supply configuration, the power supplies are hot-swappable, meaning you can replace a power supply unit without powering down the SBC 5400 platform (provided that the redundant power supply is operational)
Before replacing a power supply in a redundant power supply configuration, verify that the redundant power supply's POK LED status is “solid green.” Removing a power supply when it does not show a "solid green" status may cause the system to power down. Contact Ribbon Customer Support if necessary.
Power Supply Condition | LED Status (Green/Red) |
---|---|
Standby ON, Main Output OFF, AC Present | Blinking Green |
Standby ON, Main Output ON | Solid Green |
Main Output OCP, UVP, OVP | Blinking Red |
FAN Fail, OTP, Standby OCP/UVP | Red |
AC cord unplugged; with a second power supply in parallel still with AC input power | Red |
To prevent damage from electrostatic discharge, an ESD strap is provided in the accessory kit. See Connecting ESD Wrist Strap to install it.

All SBC 5400 CRUs are shipped in electrostatic discharge bags and must be handled using appropriate ESD precautions.
The storage environment for these CRUs are:
The ESD Susceptibility symbol warns of the presence of Ribbon devices susceptible to electrostatic discharge. Do not handle equipment without wearing a properly grounded ESD wrist strap.
