T640 AC Power Cord Specifications
Most sites distribute power through a main conduit that leads to frame-mounted power
distribution panels, one of which can be located at the top of the rack that houses the
router. An AC power cord connects each power supply to the power distribution panel.
Each AC power supply has a metal wiring compartment that contains the AC terminal
block and ground labeled GND. The wye AC terminal block consists of four input terminals
labeled L1, L2, L3, and N, from left to right. The delta AC terminal block consists of three
input terminals labeled L1, L2, and L3, from left to right.
Detachable AC power cords, each 4.5 m (approximately 14.8 ft) long, are supplied with
the router. The AC power cord wires insert into the AC input terminals in the AC terminal
block by screwdriver. The plug end of the power cord fits into the power source receptacle
for your geographical location.
Table 80 on page 139 provides specifications and Figure 57 on page 139 and
Figure 58 on page 140 depict the plug on the AC power cord provided for each region
supported.
