the equipment so that it is easy to disconnect the AC power cord.
100/1000BASE-T CABLE REQUIREMENTS
All category 5 UTP cables used for 100BASE-TX connections also operate with
1000BASE-T provided that all four wire pairs are connected. However, an
enhanced category 5e cable or newer is recommended for all critical
connections or new cable installations. The category 5e or newer specification
includes test parameters that are only recommended for category 5 and comply
with the IEEE 802.3ab standards.
The VR9500 supports auto-detection of straight through and crossed cables on
all switching 10/100/1000BASE-T ports. The automatic correction of errors in
cable selection makes the distinction between a straight through cable and a
crossover cable irrelevant.
