Table 28 describes the 1-port 10GBASE-R-XENPAK module LEDs.
Table 29 lists specificatons of the 1-port 10GBASE-R-XENPAK module.
Power Module
Only one AC power module is required for the 4-slot chassis although 2 power
module slots are provided to implement N+1 redundancy. Table 31 describes the
specifications of the power module for the 4-slot chassis.
The 7-slot and 8-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 7700 systems.
