Locator function

Port LEDs can display in three different modes: SYS (the default mode), SPD (speed) and STK (stacking). The Mode button cycles through the three display modes. In the default SYS mode, SPD and STK are off. The port LEDs enter SPD display mode, indicated by the SPD LED, after pressing the Mode button one time. SPD mode helps to determine the operational speed of a port. The port LEDs enter the STK display mode, indicated by the STK LED, after pressing the Mode button a second time. STK mode is used to indicate slot presence and slot number through the first eight port LEDs. SPD and STK display modes expire after 30 seconds, and the display mode reverts back to the default SYS mode. A long press of the Mode button when in any mode other than STK mode initiates Bluetooth pairing. Models 5320-24T-4X-XT and 5320-24T-24S-4XE-XT do not support Bluetooth pairing.

The following figure shows the two alternate mode LEDs for 5320 Series switches: SPD and STK. The Mode button is used to cycle through three display modes for the port LEDs. In the default mode, SPD and STK are off. SPD and STK display modes expire after 30 seconds, at which time the port LEDs revert to the default SYS mode. Pressing and holding the Mode button initiates Bluetooth pairing.

The Mode button also supports the instant stacking feature. To instantly stack switches, first ensure that the SPD/STK LED is on STK by pressing the Mode button until the LED is green. Press and hold the Mode button for at least five seconds, then release the Mode button after five seconds. The front panel port LEDs on the primary node flash in an alternating pattern followed by a delayed reboot of all of the switches. The LEDs flash for approximately 15 seconds prior to the reboot. After the reboot completes, the switches are stacked.

Note

Note

Front-panel PoE ports use Amber to indicate PoE states.

The mode button and LEDs are located on the upper left side of the front panel on the 5320-48P/T and 5320-24P/T models. The mode button and LEDs are located on the upper right side of the front panel on the 5320-16P model.

Port LEDs in Default (SYS) Mode

In the default System mode, SPD is OFF, and the port status displays behavior for link, traffic, and PoE as described in the following table:

Note

Note

PoE is not supported on models 5320-24T-4X-XT and 5320-24T-24S-4XE-XT.

Color/State

Meaning

Green

Link is OK

Amber

Link is OK; no traffic

Green blinking

Link is OK and transmitting packets

Amber blinking

Link is OK and transmitting packets

Alternating amber and green

Port has a power fault

Off

Port has no link, or is disabled

Port LEDs in SPD Mode

The port LEDs enter the SPD display mode when the Mode button is pressed the first time, indicated by the SPD LED. SPD mode is used to help determine the operational speed of a port.

Color and blink pattern indicate speeds, as referenced by the following table.

Note

Note

Models 5320-24T-4X-XT and 5320-24T-24S-4XE-XT do not support 2.5 Gbps, 5 Gbps, and 25 Gbps speeds.

Port LEDs in STK Mode

The port LEDs enter the STK display mode after the Mode button is pressed twice, indicated by the STK LED. STK mode is used to indicate slot presence and slot number via the first eight port LED, as referenced by the following table:

Color/State

Speed

Green

The slot corresponding to the port number of the LED is present.

Green blinking

This slot has a slot number corresponding to the port number of the blinking LED.

Power LED

The power LED can indicate the status of both the internal power supply and a connected external redundant power supply (RPS), for models that support connecting an RPS. The power LED first indicates the status of the internal power supply for one second, displaying either nothing (off), a green dash, or an amber dash. The power LED then indicates the state of the external RPS for one second, displaying either nothing (off), two green dots, or two amber dots. The cycle repeats the two second interval continuously.

Note

Note

PoE is not supported on models 5320-24T-4X-XT and 5320-24T-24S-4XE-XT.
State Number Internal PSU State (dash) RPS State (two dots) LED Pattern Notes
1 On Off Green dash/off Internal PSU OK, RPS Not present.
2 On On Green dash/Green dots Both PSUs OK.
3 On Fault Green dash/Amber dots Internal PSU OK, RPS PRESENT, but failed or powered down.
4 Fault Not present Amber dash/off Internal PSU FAILed, RPS not present.

Only valid for PoE systems.

5 Fault or Off On Amber dash/Green dots Internal PSU FAILed or powered down, RPS is good.
6 Fault or Off Fault or Off Amber dash/Amber dots Internal PSU FAILed or powered down, RPS FAILED or powered down.

Only valid for PoE systems.
