Installing The Remaining Peripherals; Expansion Cabinets And Peripherals; Bus Converter And Hp-Hsc I/O Bus Converter Connections (In Pmb Slot 0) - HP 3000 99x Family Installation Manual

Installing the Remaining Peripherals

To prepare for installing the remaining peripherals:
1. Unpack the other peripherals and prepare to install them.
2. When you are ready to install the additional peripherals, power down the system:
a. Shut down the operating system. Consult the OS documentation for the appropriate
procedure.
b. Wait until the OS has finished its shutdown routine.
c. Turn the "Standby-Ready" switch on the front panel to the "Standby" position. In
this position:
i. DC power is no longer supplied to PMB cards in the cabinet.
ii. (990/992/890 Systems only) Battery back-up is disabled.
iii. Cabinet still contains AC and DC voltages.
d. Turn off power to all external HP-PB card cages by pressing the push-button switch
on the front of each of them. (Both the computer and the external HP-PB card cage
must be powered down before HP-PB cards can be installed or removed.)
e. Turn off power to the expansion cabinet(s) by placing the front power switch to the
OFF position.
f. To completely turn off all voltages in the system cabinet, turn off power switch
(circuit breaker) at the bottom rear of the cabinet. This switch disconnects the AC
line from the cabinet. No lights or fans should remain on.

Expansion Cabinets and Peripherals

If the customer's system includes additional A1884A or A1897A expansion cabinets, install
them now using the 99x/T-Class Systems Expansion Cabinet Installation Guide (PN
A1809-90006) that accompanies them.
Bus Converter and HP-HSC I/O Bus Converter Connections (in
PMB Slot 0)
In a previous step, you connected the bottom two connectors on the BC or HP-HSC I/O Bus
Converter (997/T600 Systems) to the internal HP-PB card cage. In this part of the
installation, you connect the top two connectors to an optional external HP-PB card cage.
This connection allows the card (upper port) in the PMB card cage to communicate with
the card (lower port) in the external HP-PB I/O card cage.
To make this connection:
1. Locate the two flat ribbon cables for connecting the BC or HP-HSC I/O Bus Converter
cards. These cables are 10 meters long.
