Replacing the CPU Battery, if Necessary
Replacing the CPU Battery, if Necessary
NOTE: Save the database before you replace the CPU battery (see page 6-65 for details).
10.15 The CPU128, CPU020/PCM, and CPU020/PCMA cards are each equipped with a 3.6V,
¾AA, lithium battery (part no. 815.1011) that can support the database for at least two months
of accumulated system down time.
10.16 If the battery’s voltage is not greater than 3.3VDC (as measured in step 4 on page 3-98
or 3-106), replace the battery as outlined in the following steps:
1. Turn OFF the system AC POWER switch, remove the card from its slot in the equip-
ment chassis, and place it on a clean, flat, anti-static, non-conductive surface. If neces-
sary, remove the plastic cover housing the existing battery (see Figure 3-50 on page 3-
107 or Figure 3-51 on page 3-108).
2. Remove the existing battery and dispose of it properly.
3. Observing the proper polarity, install the new battery.
4. If a plastic cover was removed in step 2, replace the cover.
5. While pressing the battery check button on the card, measure the database back-up bat-
tery voltage. The voltage test points (TP1 to TP2) are located on the front edge of the
card. Insert the “common” voltmeter probe into the ground point (TP2) and insert the
other probe into the voltage test point (TP1). If the voltage is not greater than 3.3VDC,
try another battery.
6. Replace the card in its appropriate slot in the equipment chassis and turn ON the system
AC POWER switch.
E. CALL PROCESSING (CP) SERVER
10.17 The Call Processing (CP) Server is a type of CPU for the Inter-Tel system. The call pro-
cessing software has been moved from the system CPU to a Windows NT-, 2000-, or 2003-
based server that communicates with the system via a 10Base-T Ethernet connection or via the
ATM Switch. As of version 8.0, all 512 or higher systems require a CP Server. For an ATM-
based system, the CP Server PC must be running Windows 2000 or later.
10.18 In v11.0, Windows Server 2003 (Telco version) operating system (OS) with Service
Pack 2 (SP2) is supported for the Call Processing Server (CPS). Field upgrades must be done
by certified technicians only. See page C-3 for details.
10.19 In a non-ATM system, the PC and CPU/PCM/EAC are connected directly via a cross-
connect Ethernet cable and use the UDP protocol to transfer data across a direct connection or
a LAN connection. In an ATM-based system, the PC and the ATM Switch are connected
directly via a UTP5 or multi-mode fiber (MMF) cable. The UTP5 and OC-3 connectors are
provided on the ATM Adapter card which is installed in the CP Server PC. An EAC is not
required when using the ATM Switch. For more information and specifications of the CP
Server, see Appendix C — CP Server.
10.20 Each CP Server also has a traditional Ethernet Network Interface Card (NIC) and an
internal modem. You should configure the CP Server to match the end user’s Ethernet network.
