Hardware and firmware differences
Libraries shipped before June 2012 with Control Module SKU QQ007A are likely to be Hardware
Revision 1 (HW REV1). These libraries are characterized by:
• A multi-part accessor or picker
• An X-axis gear track system
• A Library Motor Drive (LMD) board in the Control Module
• Robot power via an umbilical cable along the floor of the library
• Removable calibration targets
• An accessor installed on the Y-rail
Libraries shipped after June 2012 with Control Module SKU QQ007B are likely to be Hardware
Revision 2 (HW REV 2) libraries. These libraries were introduced to support dual robot capability,
but all single robot libraries now use this architecture. HW REV 2 libraries are characterized by:
• A new one-piece robot
• An X-axis gear track system
• A Library Power Control (LPC1) board in the Control Module, replacing the LMD
• Robot power via a power rail system
• Calibration targets that are glued in place and in new locations
• A robot which is installed via a loader bracket
• Two new boards, the SPA and SCC, used to connect the Control Module to the left Parking
Module
A library's Hardware Revision can be identified on either the Library Management Console (LMC)
or through Library and Tape Tools (L&TT). On the LMC, the Hardware Revision is displayed
prominently on the main screen under the Status, Serial #, and Date.
NOTE: If there is no “HW Revision” text displayed on the LMC, this also indicates Hardware
Revision 1.
In L&TT, the Hardware Revision is displayed under Detailed Device Information→Device.
In this document, parts that are specific to one revision or the other are called out specifically. All
other parts are common between both library types.
