The SRX3K-16GE-SFP switches 16 ports of Gigabit Ethernet traffic from either a copper or a fiber interface media. It is inserted horizontally into the midplane of the device to communicate with the Switch Fabric Board (SFB) and to receive power. To use fiber interface media, install Small Form-factor Pluggable (SFP) transceiver modules on the desired ports. LEDs on the faceplate of the IOC indicate port status and connectivity and are the same for all IOCs (see Table 1). Ports are numbered from top to bottom and left to right, 0-15. The ONLINE button does not perform any function. To power up and power down IOC, you must use the main Power button on the front of the SFB. See Figure 2.
