• Unit 4 -system LED will flash 4 times;
• The duration of each flash (LED off time) will be as follows:
• LED off time (in each flash) ~ 0.5 seconds.
• “Interim” LED on (between 2 LED offs) ~ 0.5 seconds
For example, the flash duration on unit 3 will be ~ 2.5 seconds [(3 LED off *0.5 seconds) + (2
“interim LED on” *0.5 seconds) = ~ 2.5 seconds).
• The flash on all member units will occur simultaneously. This means that the 1st flash on all member
units will occur at the same time, the 2nd flash (for units 2 and up) at the same time.
• The 20 second interval will be counted from the occurrence of the 1st flash on all member units.
This will allow the next flash cycle to begin at the same time on all units.
• If a member unit is removed from the stack, its system LED will continue to flash according to
above definition.
The following are per port LEDs:
• LINK/ACT—(Green) Located on the left of each port. The LED lights steady when a link between the
corresponding port and another device is detected, and flashes when the port is passing traffic.
• SFP+ (if present)—(Green) Located on the right of a 10G port. The LED lights steady when a connection
is made through the shared port, and flashes when the port is passing traffic.
Configuring Switches
The switch can be accessed and managed by two different methods; over your IP network using the web-based
interface, or by using the switch’s command-line interface through the console port. Using the console port
requires advanced user skills.
The following table shows the default settings used when configuring your switch for the first time.

Configuring Your Switch Using the Web-based Interface
To access the switch with a web-based interface, you must know the IP address that the switch is using. The
switch uses the factory default IP address of 192.168.1.254, with a subnet of /24. When the switch is using
the factory default IP address, the System LED flashes continuously. When the switch is using a DHCP
server-assigned IP address or an administrator has configured a static IP address, the System LED is a steady
green (DHCP is enabled by default).
