Led Behavior; Optional) Install The Stacking Module - HP Aruba 3810M Series Installation And Getting Started Manual

Table 16 Example of an 3810M-48-port PoE+ switch Label and Description
When the switch is powered on, it performs its diagnostic self test and initialization. This boot
process, depending on switch model and configuration, takes approximately 1-2 minutes to
complete.

LED Behavior:

During the switch boot:
The Global Status, UID, other Status and Mode LEDs, will initially turn on green and
bi-color LEDs will change to orange, then back to green.
The Global Status LED will start blinking green, indicating the switch is going thru its self-test
and will continue to blink green until the switch if fully booted.
The Port LEDs will come on green, turn orange, turn back to green, and then may blink on
and off during phases of the boot.
When the switch boots successfully, the LEDs display:
Global Status and Back LEDs will be on solid green.
Locator LED is off.
Other status LEDs may be on or off depending on the switch configuration and the hardware
installed.
The port LEDs go into their normal operational mode:
◦
If the ports are connected to active network devices, the port LED may be on and
behaves according to the LED mode selected. In the default LED mode (Activity/Link),
the LED should show half-bright green to indicate Link and be flickering full-bright green
to show network traffic.
◦
If the ports are not connected to active network devices, the port LED will stay off.
If the LED display is different than what is described above, especially if the Global Status LED
continues to blink green for more than 120 seconds or blinks orange continually, then the switch
boot has not completed correctly. Refer to

3. (Optional) Install the Stacking Module

NOTE: Hot swapping the Stacking Module is not supported. If a module is installed with the
switch powered on, self-test of the module will not occur, the Back LED on the front of the switch
and the Module Status LED on the module will blink orange. The switch must be reset or power
cycled for the module to function. Only insert or remove a module during scheduled downtime
with the switch powered off.
1. Remove the cover plate.
2. Insert the module aligning with the guides in the slot.
3. Once the contacts have engaged, use the extractor handles to seat the module completely.
