The maximum power values shown include a per-C7 minimum power load of 330 W, consisting of two RAP-OCn (2 x 65W), one
AMP (10W), one fan tray (70W), and one heat exchanger (120 W).
2
Calix recommends using an N+1 rectifier module scheme for redundancy. The quantity shown represents N only, with no
redundant module.
3
The max HDSL2/4 power values shown assume the max of 6 ports per card (HDSL2) configured to support line powering (DS1
Power = Source). However, in typical applications, 2 of the 20 cards would serve as standby units in 1:N protection schemes (two
1:9 groups).
