v Media bay 1 has an IDE CD-ROM.
v
Media bay 2 has a diskette drive.
Hot-pluggable disk drives
Four hot-plug disk-drive bays with a maximum of two bays used for the operating system and operating
system mirroring feature, using only 36.4 GB Ultra3 10K RPM 1-inch drives. Disk-drive bays 3 and 4 are
always empty.
PCI-X slots and integrated adapter ports
Six hot-plug PCI-X slots (64 bit, 133 MHz, 3.3 volts) are included in the NAS Gateway 500.
