LED Type

LED Position or Color

Meaning

STATUS

Off

Fan tray is not getting any power.

Green

All fans are running and the fan tray is operating normally.

Amber

One fan is not running.

Red

Two or more fans are not running.

LOCATE

Blue

Identifies the fan tray receiving the beacon signal.

The fan tray assembly has two blue beacon LEDs, one on the front panel and one on the rear. The two will always match each other.

The blue beacon LED on the front panel is also a switch that you can press, to turn the front and rear blue beacons on or off. Alternatively, you can turn the blue beacons on or off through software.

AC input voltage is lesser than 84 VAC or greater than 264 VA.

DC input voltage is lesser than 40 or greater than 72 VDC.

OUTPUT

Green

55 VDC power supply output and power supply modules are operating within regulation limits.

Blinking Green

Standby mode or sleep mode.

Blinks on for 0.5 seconds and off for 0.5 seconds.

FAIL

Off

DC output voltages have not exceeded the alarm threshold ranges.

Red

An output voltage is out of the specified range, or the power supply module's fan has failed (as sensed by lack of fan rotation), or the power supply module is turned off after input power is applied.

Illuminates for 2-3 seconds after input is applied or disconnected through the front panel On/ Off rocker switch (for AC-input power supplies) or On/ Off power button (for DC-input power supplies) or a circuit breaker.

LOCATE

Blue

Module is receiving the beacon signal.

Blinking Blue

Change in the DC-input power supply module’s power button mode.

Blinks for 3 seconds.

LED

LED Color

Meaning

STATUS

Green

All diagnostic tests have passed and the module is operational.

Amber

The module is booting or running diagnostics or the module is disabled.

Red

A test other than an individual port test has failed. On some modules, this LED turns red immediately after the system is powered on, until the software boot process begins.

Off

LOCATE

Blue

Identifies the module receiving the beacon signal.

PORT LINK

Green

Port link is up but there is no packet activity.

Blinking Green

Amber

Port link is disabled by the user, that is, administratively down.

Blinking Amber

Hardware (PHY) has detected a faulty port link.

Alternating Green and Amber

Error packets are being detected on the port link. The error packets could be bad Cyclic Redundancy Check (CRC) packets, jumbo packets, and so on.

Off

No signal is detected, the link is down, or the port is not connected.

Red

A diagnostic test failed.

Off

The supervisor module is disabled or is not powered up.

LOCATE

Blue

Identifies the supervisor module receiving the beacon signal.

ACTIVE

Green

Supervisor module is the active supervisor (in redundant supervisor module configurations).

Off

Supervisor module is in standby mode (in redundant supervisor module configurations).

MANAGEMENT

Green

The 10/100/1000 BASE-T Ethernet management port is operational (link up).

Off

No signal is detected for the 10/100/1000 BASE-T Ethernet management port, or there is a link configuration failure, or the link is disabled by user (link down).
