The following connectors and LEDs are also located on the front panel of the RMC:
• Stack connector—38 circuit ipass connector used to expand the system management network by
connecting to a second RMC
• WAN port—RJ45 port used to connect to the customer’s LAN or an in-rack administration node
• AUX port—RJ45 port currently is non-functional (reserved for future use)
