Step 3. Checking the Customer Environment
Check the customer environment as follows:
v
Verify with your installation planning representative or the customer that any
station-protector boxes used are correctly installed according to the
Site and
Hardware Planning Information manual.
v
Make sure the customer is aware that the recommended temperature for this system
is 24° C (75° F) and the recommended relative humidity is 45%. The following are
the acceptable operating ranges:
– Temperature - 10° C (50° F) to 38° C (100° F)
– Humidity - 8% to 80%
v
Make sure the customer is aware that the front and rear service clearances around
the central electronics complex (CEC), primary I/O, and secondary I/O drawer and
rack should be 36 inches (900mm). The service clearances are important for proper
air circulation, weight distribution, and safety for both the service representative and
the customer.
Step 4. Checking Customer Outlets
CAUTION:
Do not touch the receptacle or the receptacle faceplate with anything other than
your test probes before you have met the requirements in substep 8 below.
This system may be configured as 220 V ac or -48 V dc power. If the system is going
to be used in a dc environment, you will need to have dc power cables, and a dc power
supply.
Check the customer outlets as follows:
__ 1. Have the customer locate and turn off the branch circuit CB (circuit breaker).
Attach tag S229-0237, which reads “Do Not Operate.”
Note: All measurements are made with the receptacle faceplate in the normally
installed position.
