Table 36 describes the 1-port 10GBASE-R-XENPAK module LEDs.
Table 37 lists specifications of the 1-port 10GBASE-R-XENPAK module.
Power Module Only one AC power module is required for the 4-slot chassis, although two power
module slots are provided to implement N+1 redundancy.
The 7-slot chassis provides three power module slots to implement N+1
redundancy. However, two power modules are sufficient to power one of these
fully loaded Switch 7750 systems.
