VSU-7500 User Guide
Both cooling fans are hot-swappable and can be replaced without powering down
the VSU-7500. Refer to Chapter 4, Troubleshooting, for instructions on replacing
a defective cooling fan.
Redundant Ethernet Ports
The VSU-7500 includes two dual-port 10/100BASE-T Ethernet cards, with one
card designated as the primary interface module and the second card designated
as the secondary interface module. Both the primary and secondary interface
modules includes a public and private interface port. A failure on either primary
interface port (public or private) will result in an automatic failover to the
corresponding secondary interface without any disruption in service.
If a failover condition occurs, error messages are sent to the console port and
management workstation.
NOTE: The dual-port 10/100BASE-T Ethernet cards are enclosed in the tamper-
evident case and may be replaced only by an authorized service technician.
The status indication of the LEDs on each of the four Ethernet ports are shown in
Figure 1-3 below:
