Replacing Units in Service (“Hot-Swapping”)
In the event that a VS1000 needs to be removed from service, it is
possible to replace it with another VS1000 without taking down the
network server. The procedure for doing so varies depending on your
network operating system.
Under Windows NT, this is done through the Setup program. See the
Windows NT section of this guide for more information.
Under Novell NetWare, this is done through the vs1man program. See
the Novell NetWare section of this guide for more information.
Note: Do not use “hot-swapping” to add or remove VS1100 expansion
units. The VS1000/VS1100 combination being swapped in
must have the same total number of ports as the VS1000/
VS1100 combination being taken out of service.
Provided the number of ports remains the same, VS1100 expansion
units may be “hot-swapped” without further configuration changes.
However, be sure to power down the VS1000 base unit before
disconnecting or reconnecting VS1100 expansion units.
