Warning
When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the
card. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the
midplane or backplane with your hand or any metal tool, or you could shock yourself.
Before removing any port adapter, gracefully shut down the interface so that thre is no traffic running
through the port adapter when it is removed. Removing a port adapter when traffic is flowing through
the ports can cause system disruption.
The Cisco 7401ASR router supports OIR of the port adapte r. However, if you choose to power off the
router to remove or install a port adapter, turn the power switch to the off position and then remove the
power cable. After you have replaced the port adapter or inserted afiller panel, replace the power cable
and then turn the power switch to the on position.
Note After powering off the router, wait at least 30 seconds before powering it on again.
Follow these steps for inserting and securing a port adapter:
Step1 Attach an ESD wrist strap between you and an unpainted chassis surface. For wrist straps with a banana
jack, insert the banana jack in its grounding hole locat ed o n t h e fro nt o f th e chas sis, n ea r t he STATUS
