DGS-1250 Series Gigabit Ethernet Smart Managed Switch Hardware Installation Guide Installing Transceivers into the Transceiver Ports The Switch is equipped with Small Form-factor Pluggable (SFP) and Enhanced Small Form-factor Pluggable (SFP+) ports that can be used to connect various other networking devices to this switch that do not support the standard RJ45 wiring connection. These ports are generally used to connect this switch to optical fiber connections and can be used to connect devices to the Switch over great distances. The maximum distance that the RJ45 wiring connection can reach is 100 meters. Fiber optic connections can span several kilometers. The figure below illustrates how to properly insert SFP/SFP+ transceivers into the Switch's SFP/SFP+ ports. Figure 2-4 Inserting transceivers into the transceiver ports The SFP/SFP+ ports also support other transceiver form factors like SFP and SFP+ transceivers. A complete list of SFP/SFP+ transceivers, compatible with this switch, can be found in the SFP+/SFP Ports section in Appendix A Technical Specifications at the end of this document. NOTE: Only use pluggable optical modules and Direct-Attach Cables (DAC) that meet the following regulatory requirements:  Class 1 Laser Product  UL and/or CSA registered component for North America  FCC 21 CFR Chapter 1, Sub-chapter J in accordance with FDA & CDRH requirements  IEC/EN 60825-1/-2: 2007 2nd edition or later, European Standard Power On (AC Power) Plug one end of the AC power cord into the power socket of the Switch and the other end into the local power source outlet. After the system is powered on, the LED will blink green to indicate that the system is booting up. 11
