System Installation Installing the Other Plug-In Cards
If AC-to-DC converters are used, also check their jumper settings as previously described. If
all of these conditions are met, replace the card on which the green LED fails to light; that card
is faulty.
2.7 Installing the Other Plug-In Cards
Also install the remaining cards into their designated chassis slots.
Some cards have on-board switches or jumpers that you must set before insertion into the
chassis. These cards and their settings are summarized at the beginning of this chapter. Also
refer to the associated card reference guides for detailed instructions for each card.
2.7.1 Interface Card
Install an Interface (INF) Card into the IF slot of the chassis. Only one INF card is used in each
system. This card provides the connections to the external user interface control systems,
alarm reporting facilities, and T1 and/or E1 networks.
2.7.2 CPU Cards
Install a CPU-3 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. After
installing these cards, verify that the green LEDs light on their faceplate. If their yellow LEDs
light instead, replace the associated cards.
2.7.3 WAN Cards
Install the Wide-Area Network (WAN) Cards into the W1 through W4 chassis slots. Each
system can have up to four WAN cards. Each card also requires the proper type of
daughterboard modules (T1 DSX/E1 CEPT, T1 CSU, or 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 light on their faceplate. If their
yellow LEDs light instead, replace the associated cards.
2.7.4 Server Cards
The integrated access system offers various types of server cards, such as ADPCM. 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 this card.
