HotSwap
The PRO/100 CardBus adapter currently supports HotSwap during
connection to a network or host computer from a CardBus computer only if
you are running versions of Windows 95 or Windows NT that fully support
CardBus. This feature allows the CardBus to be removed from the
computer, temporarily replaced with another type of card such as a modem
or memory card, then reinserted without loss of network connection.
For example, a user could replace a PRO/100 CardBus adapter connected to
a network with a PC Card flash or SRAM memory card. The network drives
become temporarily inaccessible. Any access from DOS or Windows will
return an “Invalid drive specification” message. Meanwhile, the drive
associated with the flash or SRAM card is available for copying and data
retrieval.
If the PRO/100 CardBus is returned to the PC Card slot within the timeout
period specified by the network operating system, then network drives,
path, and mappings will be reinstated exactly as they were before the swap.
The default timeout value varies for different network operating systems.
On NetWare 3.11, for example, the default setting is 15 minutes and is
modifiable only by the network administrator. If the 15 minute limit is
exceeded, the network connection can usually be restored by simply
logging back in without rebooting.
NOTE:
The HotSwap feature is not supported unless Card and Socket Services software (or
its equivalent under Windows 95 or Windows NT) supports CardBus and is running
on the PC Card computer. Upgrading to new drivers from Intel may also be re-
quired, as new Card and Socket software is released.
Power Management Suspend/Resume
Power management features such as suspend/resume are supported by the
PRO/100 CardBus adapter on PC Card systems running both Card and
Socket Services (or the equivalent functionality of Windows 95 or
Windows NT) that support CardBus. This means that when the computer
enters a reduced power or power saving mode, an ongoing network
connection will remain active for the period of time allowed by the network
operating system. Even if the time period is exceeded, the network
connection can usually be restored by simply logging back in without
rebooting.
