Notes:
1. The 1.8 meter rack has six EIA units of space remaining. This space will be filled with a three-EIA
filler panel and three of the one-EIA filler panels.
2. Only the 4.3 m (14 ft) power cord features are offered for racked 9406-270 systems. There are a total of
four power cords that are routed through cable management arms. Also, there is a cable management
device that might be used to restrict the length of the power cord exiting the bottom of the rack. See
model 9406-270 Cable Poster Addendum included with the 0551 model 9406-270 rack.
3. The rack does not have power distribution. Each model 9406-270 and 7104 requires a power cord of
sufficient length to reach the receptacle. The power cord feature codes for model 9406-270s must be
used to determine the appropriate receptacles.
