Warning!
!
Do not connect a PORTS module to PortServer II while power is
switched on. This may cause severe electrical problems or dam-
age to PortServer II and the PORTS module.
Note:
You may experience performance degradation when using expansion modules
under heavy data throughput. For example, if you have a total of 64 ports, you
can drive some (but not all) ports at 115.2Kbps. The available WAN band-
width on PortServer II is approximately 3.7Mbps; the maximum port speed
for any given port is either 115.2Kbps, or whatever portion of 3.7Mbps is not
currently in use by other ports that are simultaneously active.
