Type 9306 Models 4QS, 4QX, 9QS,
9QX, 9TS, 9TX
Features
The 9306 IBM PC Server Rack Enclosure, models 4QS,
9QS, 9TS come in three primary models.
19-inch Quad Primary Server Rack, Model 9QS
19-inch Tri Primary Server Rack, Model 9TS
24-inch Quad Primary Server Rack, Model 4QS

Servers. The Tri Primary Server Rack can house up to
three IBM PC Servers.
Both Quad and Tri Primary Server Racks provide a built in
server selector which connects to one set of console
devices (monitor, keyboard, and mouse.) The server
selector works independently from the server's operating
systems, enabling the connected servers to run different
operating systems.
These IBM 9306 PC Server Rack Enclosure models are
shipped preassembled and pre-cabled.
IBM PC Server Expansion Rack Models
Three optional IBM PC Server Rack Expansion models are
available to expand the capacity of the IBM PC Server
Rack Primary Enclosure. The optional IBM PC Server
Rack Expansion models are:
19-inch Quad Expansion Rack, Model 9QX
19-inch Tri Expansion Rack, Model 9TX
24-inch Quad Expansion Rack, Model 4QX
The IBM PC Server Rack Expansion models allow the
installation of up to four more servers using the Primary
IBM PC Server Rack monitor, keyboard, and mouse.
