18 500 Series Stackable Managed Switches
• The 500 and 500X switches support the following SFP+ Copper Cable
modules for stacking: SFP-H10GB-CU1M, SFP-H10GB-CU3M, and
SFP-H10GB-CU5M.
• SFP interface is a combination port, shared with one other RJ-45
interface. When the SFP is active, the adjacent RJ-45 port is disabled.
• The LEDs of the shared RJ-45 port light to respond to the SFP interface
traffic.
Front Panel LEDs
Master—(Green) Lights steady when this switch is a stack master.
Fan—(Green) Lights steady when the cooling fan is operational, blinks
green if there is a failure.
System LED—(Green) Lights steady when the switch is powered on, and
flashes when booting, performing self tests, or acquiring an IP address. If
the LED flashes Amber, the switch has detected a hardware failure.
Stack ID—(Green) Lights steady when this switch is stacked and the
corresponding number indicates its Stack ID. When a switch has a Stack ID
greater than 4, a combination of the LEDs will light up to add up to the
Stack ID. For example, Stack ID #5 is LED#1 and LED#4, Stack ID #8 will
show LED#1, LED#3 and LED#4.
NOTE The above LEDs are found on each model of the switch. The
following LEDs are only present on switch models that have those
capabilities:
LINK/ACT LED—(Green) Located on the left of each port. The light is
steady when a link between the corresponding port and another device is
detected. Flashes when the port is passing traffic.
PoE (if present)—(Amber) Located on the right of a PoE port. Lights steady
to indicate that power is being supplied to a device attached to the
corresponding port.
100M LED (if present)—(Green) Located on the right of the port. Lights
steady when another device is connected to the port, is powered on, and a
100 Mbps link is established between the devices. When the LED is off, the
connection speed is under 100 Mbps or nothing is cabled to the port.
XG LED (if present)—(Green) Located on the right of a 10 G port. Lights
steady when another device is connected to the port, is powered on, and a
10 G link is established between the devices. When the LED is off, the
connection speed is under 10 G or nothing is cabled to the port.
