Network Storage Option Card
Introduction The 6500 PLUS network storage option (NSO) card expands basic node memory for
support of large packet sizes.
NSO Card
Description The NSO card has a 3.5-inch high-density floppy disk drive with a storage capacity
of 1.4 Mbytes (MS-DOS–formatted disks). The disk drive is used to download new
and optional software to the node. The card contains 1 Mbyte of DRAM, which can
be increased in 2-Mbyte increments to 5 Mbytes by inserting SIMMs.
The MEM lights on the front panel indicate the amount of NSO RAM used by the
system. A node with a lot of memory in the processor card may not use all the
memory in the NSO card. In this case, only some of the lights on the NSO card may
come on.
