RSP and RP Port Connection Guidelines
Inter Chassis Synchronization Port
The nV Sync 0 and nV Sync 1 ports on the RSP-440, RSP-440 Lite, RSP880-LT, and RSP-880 are the RJ-45
inter-chassis synchronization clock interfaces for synchronizing frequency and time.
CMP Port
The Connectivity Management Processor (CMP) on the RSP-440, RSP-440 Lite, RSP880-LT, and RSP-880
is a secondary, lightweight processor that provides a second network interface to the system. Each CMP
contains its own RAM, bootflash, and front panel management Ethernet port.
The CMP port provides the following functions:
• RSP4 ROMMON console access through the CMP port. This eliminates the need to use external terminal
servers.
• SSH/telnet into a designated CMP port.
RSP Compact Flash Slot
The Cisco ASR 9000 Series Router RSP cards support a single ATA/IDE type I/II compact flash external slot
accessible on the front panel. The compact flash slot has a door that can be closed whether a compact flash
device is present or not. The file systems supported on compact flash are DOS/FAT or QNX4. The compact
flash comes with a DOS format.

The RSP-440, RSP-440 Lite, RSP880-LT, and RSP-880 cards do not have an ATA/IDE type I/II compact
flash external slot.
USB Port
The RSP-440, RSP-440 Lite, RSP-880, RSP880-LT, and Cisco ASR 9922 Router RP cards have a single
external Universal Serial Bus (USB) port. A USB flash memory device can be inserted to load and transfer
software images and files. This memory device can be used to turboboot the system or as the installation
source for Package Information Envelopes (PIE) and Software Maintenance Upgrades (SMU). This memory
device can also be used for users' data files, core files, and configuration backups.
