Step 10 To remove the extractor assemblies from the upstream module, press the extractor catch release button on both the
extractor assemblies and pull them up.
What to do next
Replace the Upstream PHY module.
Installing the Upstream PHY Module in the Interface Line Card
The Upstream PHY module is installed as a replacement or an upgrade from downstream D3.0 module to a
downstream D3.1 module.
Before you begin
Prerequisites
• Attach an ESD-preventive wrist strap to your wrist and connect its end to the grounding lug that is
connected to the chassis.
• Be aware if the weight and size of the equipment. Handle the equipment with care.
Required Tools and Equipment
• ESD-preventive wrist strap
• T10 Torx-blade torque screwdriver
• 3/16" flat-blade torque screwdriver
• Configured replacement RF line card or line card blank
• Upstream D3.1 modules for upgrade
• Antistatic mat or bag
Step 1 Align the guide holes on the module with the alignment posts on the RF line card.
Step 2 Firmly press the module down to seat the connectors. Do not use excessive force.
Step 3 Tighten all the four T10 securing screws in clockwise direction to a torque of 8 pound inch.
Step 4 Snug-tighten all the screws in the clockwise direction in the same order as done in the previous step.
What to do next
• Remove the replacement RF line card or the line card blank from the chassis.
• And then install the upgraded RF line card in the chassis.
• Verify whether the version of the control FPGA is displayed as 00020009 using the show platform diag
command.
• Verify whether the PID of the upstream PHY module on the upgraded RF line card is displayed as
CBR-D31-US-MOD using the show diag slot slot_number eeprom details command on the Supervisor.
