Online Insertion and Removal (OIR) of DFCs

Chapter 2 Dial Feature Card and Carrier Card Guidelines

Online Insertion and Removal (OIR) of DFCs

Universal access (analog modem or digital calls) is supported when an interface is configured for ISDN PRI signaling. PRI signaling is available for both T1 and E1 trunks.

In any single DFC slot, you can install your choice of:

One T1, E1, or T3 dial feature card

One universal port card

Online Insertion and Removal (OIR) of DFCs

All DFCs on the Cisco AS5350 and Cisco AS5400 chassis support online insertion and removal (also known as hot swapping). You can install, remove, replace, and rearrange the DFCs without turning off the chassis power.

When the chassis detects that a DFC is installed or removed, it automatically runs diagnostic and discovery routines, acknowledges the presence or absence of the DFC, and resumes chassis operation without any operator intervention.

See:

Chapter 3, “T1 and E1 Dial Feature Cards,” to perform OIR of the T1 or E1 DFC.

Chapter 4, “T3 Dial Feature Card,” to perform OIR of the T3 DFC.

Chapter 5, “Universal Port Dial Feature Card,” to perform OIR of the universal port DFC.

Removing and Installing Populated Carrier Cards

Caution The carrier cards that carry the DFCs are not hot swappable. Removing a card while the system is still powered on may cause permanent damage to electronic circuits on the card.

The DFC carrier card plugs into one of the backplane slots and supports two DFCs. The carrier card increases backplane capacity and allows OIR of the DFCs. (See Figure 2-1.)
