Description
The LH1350C module has a bootable ROM socket. The two LED indicators,
LINK/ACT and FDX located on the bracket, show network/board link, activities,
collision, and full-duplex statuses. See Figure 1.
LH1350C module installation
CAUTION: Wear a grounding strap and observe electrostatic discharge
precautions when installing the LH1350C module. Failure to observe this caution
could result in damage or failure of the LH1350C module.
To install the LH1350C module, do the following:
Important: Install the LH1350C module in a “master slot” only.
1. Locate a master slot on the PC workstation or file server.
2. Remove the cover from the PC workstation or file server—keep all screws.
3. Remove and keep the screws holding the cover over the installation slot.
4. Carefully slide the LH1350C module into the “master slot,” aligning the
module with the slot guides.

5. Ensure that the module is firmly seated in the slot.
6. Use the screws from step “3” to secure the module to the workstation or
file server housing.
LH1350C module configuration
For motherboards with automatic PCI configuration:
• No specific setup is needed.
• You can enter the system BIOS setup menu to view or specify the interrupt
(INT) line of the PCI slots.
For motherboards with bus master and interrupt jumpers:
• Enable bus master operation in a selected PCI slot and select an INT
request line (IRQ) level, using the appropriate motherboard jumper.
• Enable I/O on the LH350C slot.
PCI bus system and configuration
• Ensure that the PCI machine supports master slots, and INT multiple
sharing and timing compatibility.
• DO NOT install LH1350C in PCI slave slots. Please refer to your PC
system manual and select the appropriate configuration settings.
• When installing multiple LH1350C modules in a server station, you should
correctly configure the IRQ settings of the PCI slot.
• Up to four LH1350C modules can be installed in a PCI file server running
NetWare operating system.
• LH1350C server modules share the same INT line with the driver
supporting multiple INT services at a time. The IRQ of each LH1350C
module should not conflict with other boards.
• Operation in full or half-duplex (default) mode is configured by LAN
driver options. The operating mode should match the working status of the
remote link device.
• Use EMM386 version 4.49 or higher, and install both DOS and EMM386
from the same DOS package to avoid software problems.
