AS4000 AC Setup and Test
Access Concentrator: Turn-Up and DC measurements
Pre-Checks
Before commencing the turn-up of the rack check that the serial number and Rev levels of all
card have been entered into the test form and that the SC boot chip version is recorded.
DO NOT power up or plug any cards fully into their slots at this stage.
Router Port Availability. If the Sitespan Server is located at the NMC and connected via a
router confirm the IP address for the router at the AC and the port for connection (typically a
RJ45 cabled to the AC from the back of the router.
Apply a loopback on the designated router port (pins 3 to 6 on an RJ45).
Check that the router at the AC can be pinged and the loopback seen from the Sitespan
Server PC at the NMC by using a simple communication application as hyper terminal at the
COM port intended for Sitespan use.
Isolate all E1/T1 cables from the AC by removing the links at the DDF.
Disconnect all cards from the backplane by pulling forward in the card guides so that the
power will not be applied to the cards when the shelf is switched on.
Rack Turn-Up and Measuring Input Voltage (Test 1a)
This section describes the procedure for measuring and connecting DC to the rack, checking
that the cards have the correct alarm indications on power-up and measuring the PSU output
voltages.
Unscrew retaining screws on the face of the Fuse and Alarm Panel. Hinge forward the panel
and using the DMM measure and record the Exchange DC voltage supply across the input
terminals (TB1(-); TB2+;.for Supply 1 and TB4(-); TB5(+) for supply 2). Check that the polarity
is correct. Ensure that the voltage measured complies with the site nominal voltage and is
within the limits specified on the test results sheet.
Test Voltage
Record the measured voltage on the test results sheet.
