CAUTION:
With the introduction of additional features for the Series 5
system, it becomes imperative that personnel turning up an RT
bank assembly use care when making settings on circuit packs
(CPs) being installed and ensure that the correct codes of CPs
are installed into the proper slots in the RT bank assembly.
Failure to observe these cautions may result in immediate or
future loss of service or may introduce errors into the digital
bitstream. Accurate facility records should be used to
determine correct CP code, bank slot position, and to make all
CP option switch settings. Listed below are several indications
that the craft personnel may use to determine whether an error
has been made during RT bank turnup:
• When a CP is installed, the CP FAIL indicator (LED) should
be observed to ensure that it comes on momentarily, then
goes off. The absence of this just powered up (JPU) indica-
tion should cause the craft personnel to check for proper
CP type, option settings, and location.
• A misplaced or misset CP should always cause the associ-
ated digroup indicator (on the BCU) to light.
• If the FAIL LED stays on following the installation of a com-
mon unit, the CP is probably failed or in the wrong position.
This indication does not always occur due to system
design.
• The following procedure may be used when a problem is
indicated (as above) following installation of a CP. A simple
verification of craft personnel error may be made as fol-
lows: While observing the FAIL LED on the CP just
installed, depress the ADU LAMP TEST switch. With the
exception of an ADU CP, if option switches on the CP just
installed are set incorrectly, the FAIL LED on the CP will
not light.
!
CAUTION:
In dusty areas (for example, near construction sites), Lucent
Technologies recommends tenting the RT cabinet to protect
electronic equipment whenever cabinet doors are open for
extended periods.
