Storage/Control I/O Module

The Storage/Control I/O Module performs two functions: to connect outside interfaces to the system controller and to house the hard disk drive. It plugs into the back of the VCO/4K system and provides the I/O interfaces for system peripheral devices and host communication links using four serial ports, one Ethernet port, one printer port and one SCSI connector. Figure 4-1 shows the front panel of the Storage/Control I/O Module.

Physical interfaces to host computers and peripheral devices are provided on the front panel of the Storage/Control I/O Module. Two serial ports are available for SIO host links, and another two are dedicated to supporting the local system administration console and a remote maintenance modem. An Ethernet Transceiver interface and parallel printer connector are also located on the Storage/Control I/O Module.

Chapter 4 Storage/Control I/O Module

Description

Serial Ports 3 and 4

Serial Ports 3 and 4 are available for Serial I/O (SIO) links between the system and a host computer. These standard female DB-25ports carry Asynchronous Data Link Control (ADLC) protocol signals between the host and the system overEIA/TIA-232cables. Pin and signal assignments for port 3 is the same as Serial Ports 1 and 2. Refer toTable 4-2 for port 4 pin and signal assignments.

Wiring conventions for physically connecting a host computer to a SIO port are provided in the Cisco VCO/4K Hardware Installation Guide. Jumpers on the Storage/Control I/O Module allow Serial Ports 3 and 4 to be configured as modem (DCE) terminations for connection to a terminal or configured as terminal (DTE) terminations for connection to a modem. Refer to the“Serial Ports 1 Through 4 and Jumper Settings” section on page 4-11 for more information on jumper configurations.

Data communication parameters for each host link must be defined in the system database using the Host Configuration screen following system power-on.Refer to theCisco VCO/4K System Administrator’s Guide for instructions on defining host links.

Ethernet Interface

The CPU employs a Local Area Network Controller for Ethernet (LANCE) to implement an Ethernet transceiver interface. The balanced transceiver signal lines from the CPU are coupled to an onboard transformer to signal lines that go through the SWI, Outer B/P and control midplane cards, and terminate on the industry-standardDB-15connector on the Storage/Control I/O Module faceplate. Pin and signal assignments for thisDB-15port are listed inTable 4-3.

To implement Ethernet links, you must purchase the optional Ethernet Communications Package available from Cisco Systems. This package contains supporting software and the Cisco VCO/4K Ethernet Guide which covers the cabling requirements and implementation strategies. You must provide cables, transceivers and other components to establish Ethernet links.

Printer Interface

The printer interface on the Storage/Control I/O Module front panel supports parallel system printers through a 36-pinCentronics-typeconnector.Figure 4-7 shows the cable wiring diagrams for connecting the Storage/Control I/O Module parallel port to the system printer.

Note The End of Line (EOL) terminator for the system printer must be defined in the system database via the Peripheral Configuration screen prior to use (refer to theCisco VCO/4K System Administrator’s Guide for more information).

Note You can use a36-conductor,straight-throughparallel cable to connect a printer to the system controller. However, only the conductors shown inFigure 4-7areused. For more information on the parallel36-pinCentronics cable available from Cisco Systems, refer to theCisco VCO/4K Hardware Planning Guide.

SCSI Interface

The SCSI mass storage bus interface on the Storage/Control I/O Module is not used in system operation.

Hardware Configuration

This section outlines hardware configuration options.

SCSI Termination Configuration

The SCSI Interface connector is reserved for future use.

Serial Port Configuration

Serial Ports 1 Through 4 and Jumper Settings

Serial ports 1 through 4 on the Storage/Control I/O Module can be configured as modem (DCE) terminations for connection to a terminal or configured as terminal (DTE) terminations for connection to a modem. (Refer to the “Serial Ports 1 Through 4” section on page 4-12 for more information.)

Jumpers are positioned in J1 for Serial Port 1 (master console), JP17 for Serial Port 2 (remote maintenance modem, and JP13 and JP18 for Serial Ports 3 and 4 (SIO host links), respectively.

For Serial Ports 1 and 2, these jumper settings assume that straight-throughEIA (DCE to DTE) cables are used to connect the system to the master console and remote maintenance modem. If the jumpers are moved to position JP11 (for the master console) and JP16 (for the remote modem), crossover cables can be used.

Note Straight-throughcables directly link the connector pinouts fromend-to-end.In crossover cables, Pins 2 and 3 are crosswired; Pin 2 at one end is wired to Pin 3 at the opposite end, and vice versa.

Jumper settings for Serial Ports 3 and 4 (SIO host links) are determined by two factors: the type of cable employed (straight-throughor crossover) and the host termination at the end of the cable (terminal or modem).

The default jumper settings for Serial Ports 3 and 4 configure the CPU as a DTE termination. This configuration supports the following arrangements:

Straight-throughcables connecting the system to a modem (DTE to DCE)

Crossover (null modem) cables connecting the system to a terminal (DTE to DTE)

Chapter 4 Storage/Control I/O Module

Hardware Configuration

You can position the jumpers in locations JP13 and JP18 (under the “To Terminal” etching) to configure the CPU as a DCE termination. Moving the jumpers to these locations supports the following SIO connections:

Straight-throughcables connecting the system to a host terminal (DCE to DTE)

Crossover (null modem) cables connecting the system to a modem (DCE to DCE)

Refer to the Cisco VCO/4K Hardware Installation Guide for more information on serial cable requirements.

Note When modifying jumper positions on Storage/Control I/O Module boards, you must move all seven jumpers to the new location to ensure operation.

Serial Ports 1 Through 4

Serial ports 1 through 4 can be configured as a modem (DCE) for connection to a terminal, or terminal (DTE) for connection to a modem. The Storage/Control I/O Module card’s serial ports are configured for shipment in the DCE configuration. Table 4-4 illustrates jumper positions for DCE and DTE.

Step 1 Remove the Combined Controller that is connected to the Storage/Control I/O Module to be serviced. Refer to theCisco VCO/4K Card Technical Descriptions for information on how to remove the Combined Controller.

Step 2 Use a1/8-inchbladed screwdriver to loosen the captive mounting screws at the top and bottom of card. Do not remove the screws from the cards.

Step 3 Grasp the screws at the top and bottom of the card and pull the card away from the midplane.

The card fits tightly into the midplane connectors and some force is required to pull it away from the midplane. However, do not exert excessive force on the card to remove it.

Step 4 When the card is free of the connector, grasp the sides of the front panel and pull the card free of the card slot.

Step 5 Grasp the card on its bottom edge as it is removed from the card rack.

Step 6 When you have removed the card from the slot, place it on an antistatic mat or in an antistatic envelope.

Note Do not replace the Combined Controller until the Storage/Control I/O Module is replaced. If the Storage/Control I/O Module is not replaced at the time of removal, do not replace the Combined Controller.

To remove and replace a Storage/Control I/O Module card in a redundant system:

Step 1 If servicing an active Storage/Control I/O Module, switch the active side to standby. Refer to the maintenance chapter in theCisco VCO/4K System Administrator’s Guide for information about how to switch the active side to standby.

Step 2 When the transition to standby is complete, remove and replace the Storage/Control I/O Module.

If you are permanently removing the Storage/Control I/O Module from a nonredundant system, back up the database before powering down the system and removing the module. Refer to the Cisco VCO/4K System Administrator’s Guide for information on backing up the database.

Replacement Procedures

Caution Follow ESD rules when removing a system component. Use a wrist strap for grounding.

To replace the Storage/Control I/O Module:

Step 1 Place the replacement Storage/Control I/O Module on the antistatic mat or envelope.

Step 2 Verify that the Combined Controller that is to be connected to the Storage/Control I/O Module isnot plugged into the backplane.

Step 3 Verify that all the jumpers on the replacement card correspond with those on the removed Storage/Control I/O Module.

Verify that the jumper configuration is appropriate for the system configuration.

Refer to the “Serial Ports 1 Through 4 and Jumper Settings” section on page 4-11 for details on jumper settings for the Storage/Control I/O Module.

Step 4 Grasp the replacement card by the sides of the front panel and align it with the top and bottom card guides.

Step 5 Push the card inward until it makes contact with the midplane.

Step 6 Firmly push the card toward the midplane. The card fits tightly into the midplane connectors and some force is required to seat the card back firmly into the midplane connectors.

Step 7 Use a1/8-inchbladed screwdriver to tighten the mounting screws at the top and bottom of each card into the tapped holes on the mounting rail.

Step 8 Plug the Combined Controller into the backplane.

Step 9 If installing in a nonredundant system, make sure the system is powered on.

Step 10 If the hard disk drive does not contain the Generic software, install the software. Refer to the system release notes for instructions on installing the Generic software, backing up and restoring the database, and licensing.
