Gnss Module (A900-Cm-Gnss) - Cisco ASR 903 Quick Start Manual

• Storage of software images, system configuration, OBFL, SysLog
• PTP packet processing including IEEE 1588-2008 for recovering network timing (frequency, phase, and time) from upstream
PTP clocks, for generating PTP frequency and phase references as inputs to the SETS, and for distributing them to downstream
PTP clocks
• External management interfaces (RS232 console, management ENET, USB console, USB storage) and system status LED
indicators
Supported RSP Features
The RSP provides the following features on the Cisco router:
• Centralized data plane, timing, and control plane functions for the system
• High-level control of interface modules
• Management functionalities for the router
• Control plane (host) CPU and associated memory in which IOS-XE and platform control software runs
• Nonvolatile memory for storage of software images, configurations, and system files
• Enabling and monitoring the health and presence of fan trays, interface modules, and power supplies
• Field replacement and hot-swap capabilities
RSP Redundancy
The Cisco ASR 903 Router chassis includes two RSP slots to allow for redundant RSPs. When the router uses redundant RSPs, one
RSP operates in the active mode and the other operates in the hot standby mode. Removal or failure of the active RSP results in an
automatic switchover to the standby RSP.
Note If you are using redundant RSPs, both the RSPs must be of the same type because a mixed configuration
of two different RSP types is not supported.

GNSS Module (A900-CM-GNSS)

The GNSS module is present on the RSP3 modules. It is a pluggable module that allows direct interface with the external antenna.
Note Using a single GPS antenna input for both RSPs requires usage of external splitters.
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023
Warning
Note The GNSS module is not hot swappable.
