Opened: Jul 06, 2016
Severity: 1-Blocking

Symptoms

The BIG-IP i-Series platform (i2600, i2800, i4600, i4800) 250W AC power supply PWR-0334-01 and PWR-0334-02 will show differences in their LED behavior when hot swap or hot plug or whenever power is removed from the supply. This includes redundant systems and systems with a single supply.

Impact

LED behavior may be inconsistent between revisions of power supply on early platform shipments with PWR-0334-02

Conditions

PWR-0334-01 When the input ramps below 80Vac, the input LED Green Blinking, output LED Amber Blinking. When the input ramps below 72VAC, the input LED OFF, output LED Amber Blinking. If the AC cord is removed with 1 or 2 supplies in the system the input LED OFF, output OFF. PWR-0334-02 When the input ramps below 75VAC + 1VAC, the input LED Green Blinking, output LED Amber Blinking When the input ramps below 70VAC + 1VAC, the input LED OFF, output LED OFF immediately
