Cabinet Temperature Query Test (#122)
NONVARIABLE-SPEEDFAN ASSEMBLIES in older or upgraded
cabinets: The AHD1 circuit pack has reported an air-flow problem. The
temperature difference between the air intake and the air exhaust is at
least 15 0 C (59 0 F)) and the absolute temperature at the top of the cabinet
is at least 500C (1220F). The fans should be running at high speed. If
none of the fans are running:
1. Look for an resolve every alarm against CARR-POW (Carrier Power
Supply).
S8700-series IP-PNC Look for an resolve every alarm against
RMC-ENV (Power/Fan Sensors).
2. Verify that 48 VDC is available to the fan wiring harness connector
between pin pairs 2/3, 8/9, and 10/11. The tolerable range for this
measurement is -42.5 V to -52.5 V.
If 48 VDC is present and the fans are not running, replace the AHD1
circuit pack. If the fans still do not run, escalate the problem.
3. If 48 VDC is absent, replace the CFY1B current limiter card.
If the fans still do not run, escalate the problem.
If some fans are running and some not, replace the defective fans.
4. If every fan can be started, wait 5 minutes and rerun the test. If the
test fails again, proceed to the next step.
5. If every fan is running but not at high speed, measure the cabinet
temperature at the air intake and the air exhaust at the top of the
cabinet.
a. If the 150- /500-C criteria is met, there is a problem with the
AHD1 circuit pack or the fans. Replace the AHD1 circuit pack
and/or fans. If the fans run at high speed, wait 5 minutes for the
cabinet to cool, then retest. If the test fails, escalate the
problem.
b. If the 15 0- /50 0- C criteria is not met, environmental maintenance
is incorrectly reporting this condition. Resolve every error
(S8700-series Fiber-PNC: MAINT (PN Maintenance Circuit Pack))
and retest. If the test fails, escalate the problem.
