Expansion Module LEDs
“Expansion Module” LEDs refer to the LEDs specific to the expansion module.
These LEDs are located on the physical expansion module bulkhead. These
LEDs are only viewable in the rear of the 3500yl-48G product on the expansion
slot module itself. These LEDs are duplicated on the front panel of the 3500yl-
24G and 6200yl-24G switches. The 3500-24/48 PoE and 3500-24/48 non-PoE
switches do not have an Expansion Module LED.
Table 1-3. Expansion Module LEDs
Expansion module LEDs operate in modes for Link and Activity. FDx and Spd
modes have no meaning for the 10-GbE ports on the expansion module.
Caution It is required the switch be powered down before inserting or extracting the
Expansion Module.

Indicates that the port LEDs are displaying link information:
• if the port LED is on, the port is enabled and receiving a link indication
from the connected device.
• if the port LED is off, the port has no active network cable connected,
or is not receiving link beat or sufficient light. Otherwise, the port may
have been disabled through the switch console, the web browser
interface, or ProCurve Manager.
• if the port LED is blinking* simultaneously with the Fault LED, the
corresponding port has failed its self test.
Act Green On Indicates the port LEDs are displaying network activity information.
