Side Panels

The right side panel of the switch contains two system fans (see the top part of the diagram below). The
left side panel contains heat vents.
•
The system fans are used to dissipate heat. The sides of the system also provide heat vents to
serve the same purpose. Do not block these openings, and leave at least 6 inches of space at the
rear and sides of the switch for proper ventilation. Be reminded that without proper heat
dissipation and air circulation, system components might overheat, which could lead to system
failure.

LED Indicators

The LED indicators of the switch include Status, Speed, Full Duplex, and Link/Activity. The following
shows the LED indicators for the switch along with an explanation of each indicator.
•
Status – This indicator on the front panel blinks green when the system is booting up. It is solid
green when the system is operating normally and solid red if the system fails.
•
Speed – There are three rows of indicators for the 20 copper ports. The top LED is solid green for
1000 Mbps connections and solid amber for 100 Mbps connections. The indicator is off for 10
Mbps connections.
•
Full Duplex – This indicator for the 20 copper ports is located in the middle row. Solid green
indicates a full-duplex connection. The LED is off for half-duplex connections.
•
Act/Link – This indicator is located in the bottom row for the 20 copper ports and directly to the
left of the four GBIC ports. In each case, these indicators light solid green when there is a secure
connection (or link) to a device on any of the ports. The LEDs blink green whenever there is
reception or transmission (i.e. Activity--Act) of data occurring on a port.
