System Installation Installing the Other Plug-In Cards
3.8.2 CPU Card (8803)
Install a CPU-5 XCON Card into slot C1 of the system chassis. If redundant CPU cards are
used, also insert an identical card into slot C2. Refer to the CPU section in this manual for
details. After installing these cards, verify that the green LEDs illuminate on their faceplate.
If the yellow LEDs illuminate instead, check to see if the CPU card is registered. If the yellow
LEDs are still illuminated, replace the associated cards.
3.8.3 WAN Cards (8000 / 8010 / 8011 / 8014 / 8020)
Install the Wide-Area Network (WAN) Cards (8000, 8010, 8011, 8014 or 8020) into the W1
through W4 chassis slots. But, each system can have up to four WAN cards. Each card also
requires the proper type of sub-modules (T1 DSX/E1 CEPT, T1 CSU, Adtran E1/HDSL and
PairGain T1/HDSL), depending on whether it interfaces with a T1, E1 or DSL network. Refer
to this manual for more information on the various WAN cards currently available.
After installing the WAN cards, verify that the green LEDs illuminate on the WAN faceplates.
If their yellow LEDs light instead, check that the T1s are active. If the yellow LEDs are still
illuminated, replace the associated cards.
3.8.4 Server Cards
The Integrated Access System offers various types of server cards, including ADPCM (8871),
FRS (881160 and 881163), MCC (8813), ATM (8820), IDSN-PRI (8840), PRI-BRI (881162),
IMUX (8880) and IPR (881161, 8830 and 8831). Each system can have up to three server
cards, which fit in slots P1, P2, and P3 of the chassis. Refer to the Server Card Reference
Guide for more information on these and other server cards available with this system.
When installing server cards into your system, note that some are labeled “ACS” on their
faceplate ejectors, regardless of the type of service they provide. This label identifies the
actual card itself, which is physically the same for some server applications. However, an ACS
card can be individually software-configured as a frame relay server (FRS), management
channel concentrator (MCC), asynchronous transfer mode (ATM) server, or PRI-BRI server.
Therefore, the specific server type for each card (FRS, MCC, ATM, ISDN-PRI, PRI-BRI,
IMUX, IPR, etc.) appears only in the user interface screens, which are described in the Server
Cards Reference Guide.
