Chapter 7 NPE-G1 and NPE-G2 Installation and Configuration Information Figure 7-9 Types of SFP Module Latches 1 2 Installing the NPE-G1 or NPE-G2 3 80755 1 Sliding latch 2 Swing and slide latch 3 Swing latch Note The SFP module must be installed before you connect the cables to it. The SPF module has three types of latches, which are also the removal mechanism. See Figure 7-9. There is no correlation of the type of latch to the model (such as SX or LH) or technology type (such as Gigabit Ethernet) of SFP modules. Always read the label on the SFP module to determine the technology type, and model. You can install and remove Gigabit Ethernet SFP modules with power on to the system. Disconnect all cables before removing or installing a Gigabit Ethernet SFP module. We strongly recommend that you do not install or remove the SFP module with optical fiber cables attached to it. SFP modules are keyed to prevent incorrect insertion. Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051 Warning Class 1 laser product. Statement 1008 Warning Class 1 LED product.
