of six SAS-3 I/O ports. However, only ports A and B of each I/O module are used
to connect the storage shelf to the appliance or other storage shelves.
Each I/O module also includes one Ethernet port and a 3.5mm RS232
Interface-to-Enclosure Services Processor jack. The Ethernet port and the RS232
jack are only used during on-site debugging operations. They are not used during
normal appliance operations.
Along with the I/O modules and the disk drives, the Veritas 2U12 49TB Storage
Shelf also includes a front control panel. The control panel provides LED indications
of the health of the storage shelf. It uses a dual seven segment display for enclosure
identification and a switch that is used for storage shelf configuration purposes.
The Veritas 2U12 49TB Storage Shelf serial number appears on a plastic panel on
the left side of Power Cooling Module 0 (PCM 0). The storage shelf serial number
begins with the letters SH.
