Quantum PX500 Series User’s Guide
26
Each cartridge magazine holds 15 SDLT cartridges or 18 LTO cartridges.
The bins in the left magazines are numbered from 1 through 15 (18 in
LTO libraries) from front to back. The bins in the right magazines are
numbered from 1 through 15 (18 in LTO libraries) from back to front.
The PX502 has two fixed slots behind the right magazine. The PX506 has
twenty-eight fixed cartridge slots, nine above each left and right
magazine and ten in a column at the back of the library. PX510 has twenty
one fixed slots in a column at the back of the library. Fixed slots are used
for data cartridges, or for cleaning cartridges, which are moved to a tape
drive when the drive requires cleaning.
A bar code reader is attached to the library’s robotic hand. This bar code
reader automatically identifies the cartridges in the library, if the
cartridges are fitted with acceptable bar code labels.

System Controller Board (SCB
)
1
The system controller board (SCB) contains the library firmware and
processor. Two Ethernet ports are available for remote management of
the library. The SCB (when not in surrogate mode) also provides a
connection to a host system. There are three types of SCBs:
• SCSI SCB - provides two SCSI ports for a host connection and a
tape drive connection
• Fibre Channel SCB - provides a single Fibre Channel port for a
host connection
• Surrogate SCB (PX502 Only) - provides the ability to allow the
SCSI bus on tape drive one to also act as the media changer
