However, The cache memory installed on a slot, one of CHE0to CHE3, of CONT0 must have the same capacity as that on thecorresponding slot of CONT1. The additional control cards installed in CONT0 must have cachememories with the same capacities as those installed in CONT1 at thecorresponding slots (CHE4 to CHE7). However, their locations andcapacities may not be the same as those of the cache memories in thecontroller. Install cache memories on the slots sequentially in the ascending order ofslot numbers if they are installed.NF2300-SC01E and NF2300-SC02E are composed of two 256MB cache memory cardsand two 512MB cache memory cards, respectively.
