Chassis Cooling Fan
The VSU-10000 includes two cooling fans on the rear panel to cool the chassis.
This cooling fan assembly is hot-swappable and can be replaced without
powering down the VSU-10000. Contact your customer service representative to
obtain a replacement for the defective fan. Operation can quickly be verified by
holding an open hand near the fan to sense airflow.
Fan Removal and Replacement
Referring to Figure 4-1, perform the following steps to replace the cooling fan
assembly:
1.
Unscrew the two thumbscrews in the lower left and upper right corner of the
fan, then pull the fan straight out of the unit.
2.
Making sure that the fan’s power connector is aligned with its socket, slide
the new fan into place and tighten the two thumbscrews to secure it to the
unit.
Ethernet Interface Module
The VSU-10000 includes two single-port 10/100/1000BASE-T Ethernet cards,
one for the public and one for the private interface ports.
Removal and Replacement
The single-port 10/100/1000BASE-T Ethernet modules are enclosed in the
tamper-evident case and may be replaced only by an authorized service
technician. Contact your customer service representative or Avaya technical
support for instructions on getting the unit serviced.
