GPS Port Pinouts
The platform is capable of receiving or sourcing GPS signals of 1 PPS & 10 MHz. These interfaces are
provided by two mini-coax 50-Ohm, 1.0/2.3 DIN series connector on the front panel. Similarly there are two
mini-coax 50-Ohm connectors provided in the front panel to output this 1PPS and 10MHz.
The table below summarizes the GPS port pinouts.

USB Console Port Pinouts
Two individual Type A USB connectors are used for the USB console and USB mass storage. One USB 2.0
Type A receptacle is provided on the RSP front panel for providing console access to ROMMON, Cisco
IOS-XE, and diagnostics. This USB 2.0 Type A receptacle operates as a USB peripheral only for connections
to an external host PC. This receptacle requires the use of a Type A-to-Type A connector instead of a standard
USB cable.
The use of the USB console is mutually exclusive with the RS232 console/AUX port. When a USB cable is
inserted, access is automatically switched to this port.
Note
The other single USB 2.0 Type A receptacle is provided on the RSP front panel for inserting external USB
mass storage devices such as standard USB flash drives. It is used to load images, store configurations, write
logs, and so on, and supports up to 12 Mbps of operation.

Fiber-Optic Specifications
The specification for optical fiber transmission defines two types of fiber: single mode and multimode. Within
the single-mode category, three transmission types are defined: short reach, intermediate reach, and long
reach. Within the multimode category, only short reach is available. For information about optical SFP modules,
see the documentation for the SFP module at:
