Installing the DOCSIS MAC/PHY Interface and PIC Card
Installing RF PIC in the Cisco cBR Chassis
If you are adding more interface line cards or upgrading the existing line cards, ensure that the power modules
installed in the chassis are adequate to support the line cards.
Warning
Perform this procedure to install the following PICs:
• RF Through PIC
• RF Protect PIC
• RF PIC Blank card
To use the RF HA features, install the Protect PIC.
When HA must be configured, ensure that the Protect or Through PICs are installed in consecutive slots, with
the Protect PIC being installed in the uppermost PIC slot.
Do not leave a PIC slot empty in order to avoid critical thermal alarms relating to overheating of individual
components.
Do not install any Blank PICs between any two Through PICs or between an Protect PIC and Through PIC.
Caution
Before you begin
• If high availability (HA) configuration is required, install an RF Protect PIC in the uppermost PIC slot.
• Be aware of the weight and size of the equipment. Handle it with care.
