1.2.2 Power and Ground
The DX940e can be ordered with a high (90 -250 VAC or VDC) or Low (24-48 VDC) voltage power supply. The
connection point for the power supply is located at the rear of the chassis. The rear face also contains the primary
ground stud and labels including serial number, model number, and port and power specifications.
Shown below in Figure 1-2.
For detailed power specifications see
Power Requirements
.

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°C (185°F). Also, due to temperature rise of internal
components, it is recommended NOT to touch the device body throughout its input voltage range
as well as full operating temperature range, as the metal surfaces of the device would become too
hot to touch.
REMARQUE: l'étiquette d'avertissement relative aux surfaces chaudes est apposée sur cet appareil,
car celui-ci est conçu pour fonctionner à des températures ambiantes atteignant 85°C (185°F). De
plus, en raison de l'élévation de température des composants internes, il est recommandé de ne
PAS toucher le corps de l'appareil dans toute la plage de tension d'entrée et de plage de
température de fonctionnement, car les surfaces métalliques de l'appareil deviendraient trop
chaudes au toucher.
1.2.3 Indicators
The operational status of the ports of the DX940e is indicated by LEDs located near the physical ports on the front
of the DX940e, 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 DX940e
In Figure 1-3, the LEDs are shown for Console Port; Alarm Port; and E3 through E6. Ethernet Ports E3 through E6 are
10/100/1000 copper ports or 100Mbps or 1000Mbps 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.
