The division by 0.88 accounts for the 88% efficiency of the power
supply.
If you want to plan for future expansion, you can budget for a total of 1704
Watts power dissipation. This is equivalent to 5812 BTUs/hour.
Power Cord and Cable Requirements
Table 5.3 lists the required cables and power cords for the switch. All cables
except the AC power cord and console cable are customer-supplied.
See Appendix A
for cable-connector diagrams and pinouts.

a.NSM Gigabit Ethernet ports support automatic MDI/MDIX cross-over. This feature automatically corrects the polarity of
the attached CAT5 cable, regardless if it is a cross-over or straight-through type. However, for this feature to work, the port
speed must be set to auto (auto-negotiate) through the CLI. When the port speed/duplex is forced (auto-negotiate is
disabled), automatic MDI/MDIX cross-over is disabled, and you must cable the port using standard cross-over or
straight-through cabling.
