Installation Overview
PA-2H Dual-Port HSSI Port Adapter Installation and Configuration
6-2
When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router
to conform to EMI emissions requirements and to allow proper air flow across the port adapters. If
you plan to install a new port adapter in a slot that is not in use, you must first remove a blank port
adapter.
Removing a Port Adapter
Following is the procedure for removing a port adapter from Cisco uBR7200 series routers:
Step 1 Attach an ESD-preventative wrist strap between you and an unfinished chassis surface.
Step 2 For the Cisco uBR7246, slide the port adapter retention clip down to the unlocked
position. The retention clip remains in the unlocked position. (Refer to Figure 6-2.)
