Release Notes for Cisco RF Gateway 10 in Cisco IOS Release 12.2SQ

OL-18677-10

  New and Changed Information

The most critical function of the TCC card is distribution of the system clocking, in particular the 
DOCSIS Timing Interface (DTI). The TCC card is a DTI client interface. It supports dual DTI external 
input allowing DTI server redundancy. Based on the DTI input information, the TCC card generates 
DOCSIS 10.24-MHz clock and time-stamp information to every line card in the chassis. All clocks and 
DOCSIS information are redundant. When there is no external DTI clock, the TCC card provides an 
internal DOCSIS DTI clock and time-stamp reference.

When two TCC cards are installed, they are configured as active and backup (redundant). If the TCC 
card in the first slot is working at system power-up, it automatically becomes the active card and the TCC 
card in the second slot becomes the backup card (typically slot 13 boots as the primary TCC card and 
slot 14 as the secondary, but this is not mandatory).

In terms of the overall system high availability, the TCC cards work autonomously from the centralized 
control mechanisms. Redundant TCC cards monitor each other’s priority information so that when the 
active card fails, the active card role is transferred to the redundant backup card without loss of data.

The following is a summary of the TCC card’s functions and features:

Generates and distributes 10.24-MHz clock references and 32-bit time-stamp references to every 
cable interface line card

Drives the LCD module used to display the system configuration and status information

Proxy control mechanism (via Supervisor cards) for the RF Switch cards

Front panel LEDs providing status and alarm indicators

Provides two RJ-45 ports supporting redundant DTI server sources

RFGW-10-PWR-DC1 (DC PEM)

The Cisco RFGW-10 system is powered by redundant DC PEMs. An individual PEM is capable of 
providing 4536 watts of total output. Redundant modules work as a 1:1 redundancy configuration 
supporting current sharing and online insertion and removal (OIR) (hot swapping).

Each PEM includes two 60A input lines that operate between –40 VDC and –72 VDC input voltages. 
Proper configuration and operation requires that both DC inputs are properly wired. The PEM also 
includes an earth ground connection (this is not power return) for grounding the chassis.

DC PEM features:

Closed frame, NEBS-compliant module design

Front-to-back airflow (exhaust air exits out of the rear of the chassis)

Power input range: –48 VDC to –60 VDC

4536W power capacity

Supports OIR (hot swap) and current sharing

Supports 1:1 redundancy (system can run with a single PEM)

CLI support for status and configuration

Remote shutdown feature

Front panel LED status and alarm indicators
