RCB status LEDs
Each RCB consists of the following internal components:
• CPU—Runs Junos OS to maintain the routing tables and routing protocols.
• EEPROM—Stores the serial number of the Routing Engine.
• DRAM—Provides storage for the routing and forwarding tables and for other Routing Engine
processes.
• One 10-Gigabit Ethernet interface between the Routing Engine and Switch Fabric Board.
• One USB port—Provides a removable media interface through which you can install Junos OS
manually. The Junos OS supports USB versions 3.0, 2.0, and 1.1.
• Management ports—Two ports, one copper (RJ-45 port) and one SFP port, provide access to
management devices. Use only one of the two management ports at a time.
Use an RJ-45 connector for the copper port.
Use a fiber optic connector for the SFP port.
Do not use copper SFP or SFP-T modules in the SFP port because they are not supported.
• RESET button—When pressed, reboots the RCB as detailed below:
