NOTE: The hot surfaces warning label (
) is affixed to this device
because the device is rated to operate at
ambient
temperatures as high as 85
o
C
(185
o
F). Clearly, if the device were to be installed in an environment in which
temperatures at the upper end of its operating range were attained, the metal
surfaces of the device would become too hot to touch.
1.2.3 Indicators
The operational status of the ports of the DX940 is indicated by LEDs located near the physical ports on
the front of the DX940, as illustrated in Figure 1-1, and a bank of LEDs on the top of the chassis, as
illustrated in Figure 1-3.
Figure 1-3. Top View of DX940. See below for LED details.
In Figure 1-3, the LEDs are shown for Console Port; Alarm Port; and E3 through E6. Ethernet Ports E3
through E6 are 10/100 copper ports or 100Mbps Fiber ports (using SFPs).
Depending on the options ordered, additional LED's may be displayed in the boxes labeled "A" and "B"
(shown by the red dotted line) in Figure 1-3 above. "A" and "B" (as shown in Figure 1-3 above) can have
possible combinations of LEDs as shown in Figure 1-3(a) below.
