The EZ-Dock Port Replicator includes the multi-port adapter features of
EZ-Dock Plus (serial, parallel, external keyboard, external mouse, external
VGA monitor connectors) but does not include the additional features
(PCMCIA, SCSI and multi-media support features). The two port replicators
have the same footprint and basic connectivity features.
1.2.6.3 Notebook External Connectors
External connectors on the notebook support (as shown in Figure 1-7)
connection to a variety of external devices including:
•
External PS/2 keyboard or PS/2 Mouse
•
External VGA Monitor (with simultaneous LCD display if enabled)
•
Serial RS-232-C Port for connecting to an external serial device
•
Parallel, Bi-Directional Printer
•
160-Pin PCI Expansion Bus (PCI Bus plus sidebands) to drive a
attached Docking Systemoption
•
Infrared interface for communication with IRDA-compliant devices.
1.3 Notebook Hardware Features
1.3.1 CPU/RAM Subsystem
The Pentium-based notebook runs at a system bus speed of 50 MHz and a
processing clock rate of 75MHz. As a standard feature, the notebook
contains 8MB of 70 ns page-interleaved DRAM and 256KB of 15-ns static
RAM for external cache. DRAM memory can be expanded to 32 MB using
two DRAM Expansion Board options (expansion boards install from the
front of the notebook by removing the floppy bezel as shown in Figure 1-9).
c
Caution: The RAM module option contains components that are sensi-
tive to static electricity. When handling the module and the internal
parts of the computer, protect against static electricity by using wrist
or ankle grounding straps and grounded working mats. When moving
or storing items, use the anti-static bags supplied with the items.
The first memory option may be either 8 MB or 16 MB; a second 8 MB board
(Shuttle RAM option) can be installed onto the first expansion module as
shown in Figure 1-9.
