VIP4 Maintenance Procedures
Figure 9 Handling a Port Adapter
Caution To prevent system problems, do not remove port adapters from the VIP4 motherboard or attempt to
install other port adapters on the VIP4 motherboard while the system is operating. To install or replace
port adapters, first remove the VIP4.
Caution To prevent interface reconfiguration requirements, you should replace a port adapter with the same type
of port adapter you removed, but this is not a requirement.
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
backplane with your hand or any metal tool, or you could shock yourself.
To replace a port adapter, use the procedure that is appropriate to your port adapter type:
• Single-Width Port Adapter, page 36—For replacing a single-width port adapter on your VIP4
• Dual-Width Port Adapter, page 37—For replacing a dual-width port adapter on your VIP4
Single-Width Port Adapter
Single-width port adapters occupy one of the two port adapter slots on a VIP4. When a single-width port
adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router to conform to
electromagnetic interference (EMI) emissions requirements and to allow proper airflow through the
router. If you plan to install a new single-width port adapter in a port adapter slot that is not in use, you
must first remove the blank port adapter.
Figure 10 describes the steps required to install a single-width port adapter.
