Miscellaneous Components on the Rear Panel
This subsection describes the following, miscellaneous components that are also located on
the rear panel of the J5000 and J7000 workstations:
• Security tab
• TOC button
• I/O slots
Security Tab
The security tab, which is located at the top of the rear panel, can be used to lock the
workstation with a padlock or similar type of lock. It prevents the workstation's top and
side panels from being removed so that unauthorized persons cannot access the
workstation's internal components. Note that a lock is not provided with the workstation –
the customer must supply a lock to use with this security tab.
TOC Button
The TOC (Transfer Of Control) button interrupts the system.
I/O Slots
The I/O slots located on the rear panel are 64-bit PCI (Peripheral Connect Interface) slots,
providing I/O expansion capabilities for the workstations. There are five PCI-2X slots, two
PCI-4X slots, and one slot for power only. The I/O slots are defined as follows:
1. Power only
