The following access types are supported:
• Universal port feature card—Converts voice, fax, and dial calls into IP packets or frames by using
the Nextport digital signal processor (DSP) modules.
• Dial-only feature card—Converts dial calls into IP packets or frames by using the Nextport digital
signal processor (DSP) modules.
• Voice feature card—Converts voice and fax calls into IP packets or frames by using packet fax or
voice digital signal processor (DSP) modules (PVDM2).
Online Insertion and Removal of Feature Cards
All feature cards on the Cisco AS5350XM and Cisco AS5400XM chassis support OIR (also known as
hot swapping). You can install, remove, replace, and rearrange the feature cards without turning off the
chassis power.
When the chassis detects that a feature card is installed or removed, it automatically runs diagnostic and
discovery routines, acknowledges the presence or absence of the feature card, and resumes chassis
operation without any operator intervention.
See the following chapters for more information about specific feature cards:
• See Chapter 3, “T1 and E1 Feature Cards,” to perform OIR of the T1 or E1 feature card.
• See Chapter 4, “Channelized T3 Feature Card,” to perform OIR of the CT3 feature card.
• See Chapter 5, “Universal Port and Dial-Only Feature Cards,” to perform OIR of the universal port
or dial-only feature card.
• See Chapter 6, “Voice Feature Card,” to perform OIR of the voice feature card.
Removing and Installing Populated Carrier Cards
Caution The carrier cards that carry the feature cards 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 feature card carrier card plugs into one of the backplane slots and supports two feature cards. The
carrier card increases backplane capacity and allows OIR of the feature cards. (See Figure 2-1.)
