Removing a Port Adapter

PA-4T+ Synchronous Serial Port Adapter Installation and Configuration5-2

Note The Cisco uBR7200 series supports online insertion and removal (OIR); therefore, you do 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.)
