xStack DGS/DXS-3300 Series Layer 3 Stackable Gigabit Ethernet Switch User Manual Mounting the Switch in a Standard 19" Rack Figure 2- 3. Installing Switch in a rack Power On Plug one end of the AC power cord into the power connector of the Switch and the other end into the local power source outlet. After powering on the Switch, the LED indicators will momentarily blink. This blinking of the LED indicators represents a reset of the system. Power Failure As a precaution, in the event of a power failure, unplug the Switch. When power is resumed, plug the Switch back in. The Optional Module At the rear of the DXS-3326GSR and the DXS-3350SR resides an optional module slot. This slot may be equipped with the DEM-420X 2-port 10GE XFP uplink module, or a DEM-420CX 2-port 10GBASE-CX4 uplink module, both sold separately. Adding the DEM-420X optional module will allow the administrator to add a 2-port fiber-optic uplink module which will transmit information at a rate of ten gigabits a second. These two ports are compliant with standard IEEE 802.3ae, support full-duplex transmissions only and are to be used with XFP MSA compliant transceivers. The DEM-420CX will too transfer information at a rate of ten gigabits a second but the medium is copper, not fiber and thus is only useful for short connections of up to 15 meters. Compliant with the IEEE802.3ak standard, this module will use a 4-laned copper connector to transfer information in full-duplex mode, quickly and accurately. User beware, the cable and connector port used for this module is nearly identical to the stacking ports and cables used for stacking in the xStack Series, but can in no way be interchangeable. To install these modules in the DXS-3326GSR and the DXS-3350SR, follow the simple steps listed below. 11
