    							2.15.3 Checking The General Operating Conditions
    1. Check the green light emitting diode (LED) system status indicator. Be sure that it is on
    steady. If it is off or flashing, refer to the paragraph titledChecking the System Status
    Indicator.
    2. Refer to the user’s guide for operating information and perform a general operational test of
    the system by exercising the features from station port 10 or 11. Operational parameters are
    per the system default conditions as detailed in Chapter 4 until class of service programming
    is performed.
    3. Once the basic system is verified as operational, perform the class of service programming as
    described in Chapter 3.
    2.16 Isolating Failures
    Section 2.17 will help you to find and identify problems that might occur in the digital telephone
    system.
    2.16.1 Checking The System Status Indicator
    A green LED located on the common equipment cabinet is the system status indicator. This
    indicator light comes on when power is supplied to the system. If the indicator flashes after
    power up, it signals that the processor has failed or that the software is not operating. Unplug and
    reconnect the AC power to the power supply and observe the LED indication. If it still shows a
    flashing indication, equipment replacement may be necessary.
    2.16.2 Testing The Stations
    To test the multiline stations for proper operation:
    1. Disconnect line cord at station base then reconnect it.
    2.
    On DigiTech telephones, press and hold theMUTEbutton.
    OnImpactand Impression telephones, press and hold1on the keypad.
    Station will automatically perform self test routine.
    3. Release test button as soon as test begins. Sequence of test is as follows:
    a. indicators will light in sequence,
    b. ringer will sound—be sure volume is set to low or high,
    c. indicators and ringer will then turn off at the same time.
    4. Replace any station that does not pass the self test.

    							2.17 Loading And Up-Grading The System Software
    The DSU II contains flash memory that you load with operating software when you install the
    system and later re-load with software up-grades as they become available.
    The operating software package consists of three parts: The boot-loader EPROMs that is
    factory-installed as part of the system, and the software key and software disks that you order
    separately. The software disks include the boot loader interface disk and the operating software
    disks.
    2.17.1 Introducing The Software Key
    The software key is a hardware device to un-lock the DSU II so it can accept the system
    operating software. Factory technicians program and initialize the software key, and make it
    available in several different configurations.
    The configurations are as listed below:
    DSUII–SW01
    DSUII–SW05
    DSUII–SW10
    DSUII–SW25
    The configurations control the number of times that you can use a key to load or up-grade
    operating software into a system; however, it does not matter which DSU II system you load.
    (For example, with a DSUII–SW01 key, you can load any DSU II system one time; however,
    with the DSUII–SW25, you can load or up-grade one system 25 times or load 25 different
    systems one time—your choice.)

    							2.17.2 Introducing The Software Disks
    There are several standard 3.5-inch magnetic diskettes for each software part number. This group
    of diskettes include the boot loader interface and the system operating software. You place these
    diskettes (commonly referred to as floppy disks), into your personal computer (PC) in a certain
    order just as you would any set of program disks.
    CAUTION
    The system operating software is unique for each of the three system sizes. Be sure that you
    load the correct system software for the size system that you are installing.

    Installing The System Operating Software
    CAUTION
    In this software loading sequence, the system will prompt you to save the class of service data
    base. ALWAYS SAVE THE DATA BASE FIRST before you proceed with the software load.
    Saving the data base first ensures that you will have it available should something go wrong
    during the software loading procedure. Later, after you have finished loading the system
    software, master clear the system and reload the data base that you saved before you loaded
    the software.
    Saving The Class Of Service Data Base(Using An XMODEM-Type Communications Program)
    Use the PC and an XMODEM-type communications software program to save the DSU II
    system’s class of service data base before you load the software. The following procedure
    illustrates a typical data base down-load usingPROCOMM(produced by Datastorm
    Technologies Inc.). Other software programs are also available that you can use for this purpose.
    1. When the PC display prompts for a password, typeIS746Sor the current system password
    and pressRETURN(This causes main COS programming menu to be displayed).
    2. From main menu, make all selections necessary to perform class of service programming
    then return to the main menu.
    3. From main menu, press1andRETURN(This causes system COS programming menu to be
    displayed).
