Mixing ZR XENPAKs with Other Types
Table 31 lists the supported combinations of XENPAK types using ZR XENPAKs in a Summit X450
series switch. You can either install one ZR XENPAK and leave one slot empty or install one ZR
XENPAK and one SR XENPAK; the Summit X450 series switch does not support any other XENPAK
combinations when a ZR XENPAK module is installed. You must put the specified modules in the
specified slots, as shown in Table 31, for the switch to discover the ZR XENPAK correctly.
