HSC70 MODULE INDICATORS AND SWITCHES

All logic modules have at least one LED to indicate board status. Figure 2-6 shows the locations of these LEOs and the module utilization label. Additionally, three of these logic modules contain specific switches.

Board status-Indicates an inoperable module except during initialization when it comes on during module testing.

Board status-Indicates the operating software is running and that self-test module microdiagnostics have completed successfully.

Red Board status-Indicates an inoperable module except during initialization when it comes on during module testing.

Amber (eight LEOs) DI-Off for PROM load, on for RAM load.

D2 through D8-Upper register #2 contents.

The LEDs reflect the implemented bits of the upper error register

#2. When a microinstruction parity error is detected, the module clocks are inhibited which stops the module. The bit content of the upper error register #2 is displayed on the LEDs. See Figure 2-9 for the location of the LEDs.

Board status-Indicates the operating software is running and that self-test module microdiagnostics have completed successfully.

Board status-Indicates an inoperable module except during initialization when it comes on during module testing.

Board status-Indicates the operating software is running and that all applicable diagnostics have completed successfully.

Board status-Indicates an inoperable module except during initialization when it comes on during module testing.

Always on when the HSC70 is on (used only for engineering test purposes).

Board status-Indicates the node i~ either transmitting or receiving;

dims or brightens relative to the amount of local CI activity.

Board status-Indicates the module is in the internal maintenance mode.

2.6.1 HSC70 Module Switches

Specific switches are found on LINK (L0100-E2 or LOl18), port processor (L0107), and port buffer (LO 1 09) modules as follows:

• CI port LINK module (LOIOO.E2/LOI18)-Refer to Figure 2-6 for the CI node address switches mounted on the L0100-E2 or L01l8 module. Switches must be identically set to avoid CI addressing errors. See Chapter 3 for switch positions of Sl, S2, and S3.

• CI port processor and CI port buffer modules (HSC70 LOI07 and LOI09)-Both the LOI07 and L0109 modules have dual inline pack (DIP) switches to indicate the hardware revision level.

DIP switch positions should not be changed except as directed by a Field Change Order (FCO).

Figure 2-8 shows the location of the these switches.

• HSC70 P.ioj (LOIII)-The LOllt module contains two punch-out connector packs used to assign an unique value to the P.ioj serial number register. The switch settings should never be modified in the field.

The P.ioj module serial number is used only when a default HSC ID is generated. The

SDS-II) is a hexadecimal number uniquely identifying the HSC as a node in the cluster. This ID is usually generated by initializing the HSC70 (toggling the Init switch on the OCP) while holding in the OCP Fault switch until the INIPIO banner is printed on the console. For all other reboot cases, the HSC70 P.ioj serial number is not used.

• K.si (LOI19) data channel-See Section 2.7.1 for a description of the switchpack settings.

2.7 K.si (L0119) MODULE

The K.si (L0119) data channel module is a direct replacement for the disk data channel module (K.sdi, LOI08-YA) or the tape data channel module (K.sti, LOI08-YB). The K.si can be installed in the HSC70, HSC50 (nlodified), or HSC50.

Switch Switch Function Normal

Number Name Description Position

SWI rv.tFG Provides loop on error and single port Off external loop.

SW2 Bum in Continuous loop, assumes external loop Off and clock.

SW3 Ext loop Loops on all ports. For system or field use Off only.

SW4 Ext clock Substitutes external clock. For Off manufacturing use only.

NOTE

For initialization and normal operation, the four switches must be in the off position. Errors will occur during initialization if any of the switches are not in the off position.
