Description of the Controller Cards found in the SL4000 Library.

Solution

Understanding the controller card interconnections within the library, can be useful when troubleshooting issues. See the SL4000 Installation and Service Guide for detailed external diagrams of the cards.

Controller Card Descriptions:

Note: For the location of cards in the Base module card cage, see"Base Card Cage Component Locations" on page 4-11.

Robot Controller (LOB)
The main controller card for the robot. This card replaces the HBB, HBP, and HBZ cards of the SL3000. It communicates over the rail CAN interface to the Rail Controller (LOS).
See also "Robot Controller Card (LOB) Replacement" on page 8-2.

Library Controller (LOC)
The main library controller card located in the Base module card cage. This card replaces the HBC and PUA2 cards of the SL3000. This card essentially acts as the central "brains" of the library and runs the library software.
See also "Library Controller (LOC) Replacement" on page 4-1.

Drive Tray Controller (LOD)
The controller card for the drive tray. Each drive tray contains one LOD card. This card replaces the HBD card of the SL3000 tray. It communicates between the tape drive and the Drive Motherboard (LOEM)/Drive Switch (LOES).
See also "Drive Controller (LOD) Replacement" on page 11-3.

Network Patch Panel (LOEB)
The Ethernet bulkhead that connects the Drive Module Drive Switch (LOES) and Access Module Controller (LOX) to the Library Motherboard (LOM)/Root Switch (LOER). There are two networks: Network 1 and Network 2. For each network there are six Drive Module Ethernet ports and two Access Module Ethernet ports. For external wiring information, see "Connect the External Drive Module Drive Switch Cabling" on page 1-35 and "Connect the External Access Module Cabling" on page 1-37.
See also "Network Patch Panel (LOEB) Replacement" on page 4-5.

Drive Motherboard (LOEM)
A 1U wide motherboard that connects two Drive Switch (LOES) cards to the SAS cables connecting to Drive Tray Motherboard (LOTM/LOOA) cars. The LOEM also has connectors for PDU and power supply monitor cables.

Root Switch (LOER)
Connects the drive network (LOEB/LOEM) and robot network (LOW/LOS) to the Library Motherboard (LOM)/Library Controller (LOC). This card replaces the Ethernet switch chips on the SL3000 motherboard.
See also "Root Switch (LOER) Replacement" on page 4-2.

Drive Switch (LOES)
Connects the drive trays to the Network Patch Panel (LOEB). In the Drive Module the connection to the Network Patch Panel (LOEB) is external Ethernet. In the Base the connection is internal to the Drive Motherboard (LOEM).
See also "Drive Switch (LOES) Replacement" on page 11-1 and "Connect the External Drive Module Drive Switch Cabling" on page 1-35.

Fan Controller (LOF)
Controls the speed of the individual fans in the Base card cage fan assembly and reports the status of any fan not running at speed. It also measures the temperature of the fan assembly.
See also "Fan Assembly (LOF) Replacement" on page 4-4.

Hard Drive Storage (LOH)
Contains a 600GB hard drive and local power for the drive. The card accepts any standard dual port SAS drive in a 2.5" form factor 15.5mm tall or less.
See also "Library Storage (LOH) Replacement" on page 4-2.

FRUID Card (LOID)
Stores the serial number of a device. There is an LOID attached to the Base frame, Drive Module frame, Access Module frame, and in each drive tray.
For the LOID in a drive tray, see "Drive Tray Serial Number Card (LOID) Replacement" on page 11-4.

Key Transfer Card (LOK)
The LOK card transfers the information from an SL3000 PUK card to the library database. It is only used during an SL3000 to SL4000 upgrade. Once the library has transferred the information, you can remove the PUK card and return it to the factory for recycling.

Library Motherboard (LOM)
The main motherboard in the Base card cage that interconnects the library controller cards (LOCs) to the rest of the library. This replaces the PUM and HBM of the SL3000.
See also "Motherboard (LOM) Replacement" on page 4-6.

Safety Controller (LON)
Monitors the status of all the doors and cuts power to the rail if any door opens unexpectedly. This card replaces the PUN of the SL3000. The LON has a battery so that it can report "Door Has Been Opened" status if any door opens while the library power is off.
See also "Safety Controller (LON) Replacement" on page 4-4.

Rail Controller (LOS)
The power distribution card for the rails. This card replaces the HBS card of the SL3000. This card is connected to the Rail Motherboard (LOW) (which allows the LOS to receives ethernet packets from the Root Switch (LOER) and transmits them along the rail to the Robot Controller (LOB) and vis-versa. Drive Tray Motherboard (LOTM/LOOA) The LOOA card provides the interface between Drive Motherboard (LOEM) card SAS signal cables and the LOTM card. The LOTM card connects power and control signals to four drive trays. The LOTM and LOOA create the motherboard for each drive tray row. These cards replace the PUO of the SL3000.

Video Card (LOV)
Controls which LOC displays on the front touch screen or on a separate monitor connected to the VGA port.
See also "Video Card (LOV) Replacement" on page 4-3.

Rail Motherboard (LOW)
Allows a SAS cable to wire 10/100 Ethernet directly from the Root Switch (LOER) to the Rail Controller (LOS). This card replaces the PUW of the SL3000.

Access Module Controller (LOX)
The Access Module safety door motor controller card. This card replaces the PUX of the SL3000.
See also "Access Module Controller (LOX) Replacement" on page 9-4.

DC Converter (LOY)
Converts 48V DC from the power supplies to the 12V DC. It replaces the cPCI power supplies of the SL3000.
See also "DC Power Converter (LOY) Replacement" on page 4-3.

CAP Controller (PUZ)
Rotary CAP controller card. The CAP controllers are connected using a daisy chain cable that runs from module to module, extending in both directions from the Base Module. If a CAP controller fails, all downstream CAP controllers and CAPs will be inoperative. Downstream means any CAP further away from the Base Module than the failed CAP controller.
