2.2.3 HDD LEDs
The HDD LEDs show the statuses (activities) of the hard disks of the
hard disk array. They can be seen only when they are flashing because
they are located behind the white strip and thus not visible when off.
Figure 2-3: HDD LEDs
Each LED represents a hard disk of the array:
2 alarm LED This LED indicates that a hardware malfunction
occurred.
3, 4 LAN 1/2 LEDs Indicate that a valid network is connected to the
first/second LAN connection at the rear of the
system (see section “ATX Connector Panel” on
page 2-15).
5, 6 USB ports The USB connectors (universal serial bus) at the
front offer you the possibility to connect other
devices such as memory sticks easily.

The respective state of the system will be indi-

the system alarm and cannot be
switched mute with the mute button.
