Removing a Port Adapter
PA-4T+ Synchronous Serial Port Adapter Installation and Configuration5-2
Note The Cisco uBR7200 series supportsonline insertionand removal (OIR);therefore, youdo not
have to power down the router when removing and replacing a PA-4T+.
When a port adapter slot is not in use, blank port adapters must fill empty slots 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 the blank port
adapter.
Removing a Port Adapter
Take the following steps to remove a port adapter from a Cisco uBR7200 series:
Step 1 Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.
Step 2 Place the port adapter in the unlocked position.
• For the Cisco uBR7246, place the port adapter retention clip for the desired port
adapter slot in the unlocked position. The port adapter retention clip remains in the
unlocked position. (See Figure 5-2.)
