Installing the Novell NetWare Server Driver

This driver is installed on a Novell NetWare server running NetWare 4.1.

The \NWSERVER subdirectory on EtherDisk Diskette #1 contains the driver (3C90X.LAN ﬁle) and NetWare Loadable Modules (NLMs) needed for NetWare 4.1.

The NetWare server driver can also be used on a NetWare version 3.12 server. Contact Novell to obtain the NLM ﬁles and for instructions for installing the driver in a 3.12 environment. The NetWare 3.11 server is not supported by the 3C905B-TX NIC.

NetWare Version 4.1

This section describes how to install the NetWare server driver on EtherDisk Diskette #1 on a NetWare version 4.1 server.

To import the server driver into a NetWare 4.1 server, follow these steps:

1 Install the NetWare server software.

2 When the NIC Selection menu appears, insert

EtherDisk Diskette #1 in the drive.

3 Press Insert to add a driver externally.

4 Press F3 to change the path.

5 At the A:\ prompt, enter:

nwserver

The installation program gathers the ﬁles and prompts you for a NIC selection.

6 Select 3Com Fast EtherLink XL 10/100 Ethernet NIC.

7 Press Enter to continue the server installation.

Multiple NICs

To support more than one NIC in a server, edit the AUTOEXEC.NCF ﬁle to the following format:

load C:\SERVER\3C90X.LAN PORT=<port1> NAME=<name1> FRAME=<frametype> load C:\SERVER\3C90X.LAN PORT=<port2> NAME=<name2> FRAME=<frametype>

Port1 and port2 are the 3C905B-TX NIC’s PCI port addresses, and name1 and name2 are user-speciﬁed names assigned to distinguish the multiple NICs.

The FRAME parameter is optional. The default frame type is Ethernet_802.2. If you want the ODI server driver to support more than one frame type, then both the unique NAME= and FRAME= parameters must be paired on each load driver line. The valid frame types are Ethernet_802.2, Ethernet_802.3, Ethernet_II, and Ethernet_SNAP.

The protocols must be bound to the speciﬁc driver conﬁguration using the user-assigned unique names. The following example shows how this can be done:

load C:\SERVER\3C90X.LAN PORT=1000 FRAME=Ethernet_802.3 NAME=ADPONE load C:\SERVER\3C90X.LAN PORT=2000 FRAME=Ethernet_II NAME=ADPTWO bind IPX to ADPONE bind IPX to ADPTWO

Crossover Cable Troubleshooting Tips 4-13

Crossover Cable Troubleshooting Tips

When you work with network cabling, concentrators, and NICs from different vendors, it is possible to connect everything and still have no communication between ﬁle servers and workstations.

When there are several unknown variables, it is difﬁcult to determine which component is broken. Use these tips to isolate the problem.

1 Determine whether your equipment complies with

the 10BASE-T or 100BASE-TX standard.

This is particularly important for concentrators (hubs or repeaters).

2 Connect a straight-through cable from the PC to

the hub.

The hub performs an internal crossover so that the signal can go from TD+ to RD+ and TD– to RD–. When you look at an RJ-45 connector from the front, pin 1 is identiﬁed on the left-hand side when the metal contacts are facing up.

3 Make sure that the TD+ and TD– wires are twisted

together, and that the RD+ and RD– wires are twisted together. The example in Figure 4-7 shows 10BASE-T cabling.

4-14 CHAPTER 4: TROUBLESHOOTING

Using wires from opposing pairs can cause signals to be lost. For a 100BASE-TX cable, pins #1 and #2, and #3 and #6 must be on the same twisted strand.

Troubleshooting Hubs with Crossover Cable

When there is doubt whether a hub is performing correctly, or if the impedance settings are in question, a crossover cable can help you isolate the failing component.

1 Connect a ﬁle server and a client PC back to back with

a crossover cable to verify that the NIC and network operating system are properly conﬁgured.

2 To make a crossover cable, simply connect TD+ to RD+

and TD– to RD–.

The cable performs the crossover that is usually performed by the hub. Make sure that two twisted-pair wires are used. Figure 4-7 shows the pinouts for the crossover cable. On the straight-through cable, make sure that the wires are from the same twisted pair.

If the ﬁle server and client PC function together as a small network, then either the existing cabling or the hub is the problem.

■ If there is a proper crossover, the appropriate LED

comes on.

■ If there is a straight-through connection, the LED does

not light.

■ A blinking LED indicates that there is a polarity mismatch

(that is, TD+ to RD– instead of TD+ to RD+).

3Com PCI NICs are designed to work in any bus mastering PCI slot, preferably slot 1. Avoid any PCI slot next to an ISA slot. This is often a shared slot and does not support bus mastering.The NICs perform best in those slots that support bus mastering data transfers. Refer to your PC manual for information on which slots support bus mastering data transfers.

PCI is a self-configuring bus architecture. Most of the time you only need to install the board in your PC; PCI does the rest. However, on some PCI computers, you may be required to configure the computer’s BIOS manually after installing your PCI NIC. Refer to the owner’s guide for your PC.

ISA/EISA boards that do not properly support shared interrupts (level-triggered).

If you do not know or are unsure whether other devices or adapters in your PC support shared interrupts, then avoid using them.

Avoid using the same interrupt as your local hard drive (normally IRQ 14 for IDE drives and IRQ 11 for most SCSI host adapters), since not all hard drives support shared interrupts at this time.

Avoid using 9 because it cascades with 2. For Novell NetWare servers, avoid using IRQ 7 or

15. These IRQs only support nonshared devices and may cause problems if they are shared between two devices.

Other Devices.

2 Click PCI Ethernet Controller or the duplicate

3C905B-TX NIC entry.

3 Click Remove. 4 Restart your PC.

What is the hardware IP header checksum?

The header checksum is a field in the IP header. When the 3C905B-TX NIC receives IP data, it

computes the IP header checksum, and if an error occurred, the packet is dropped and is not passed to the protocol stack. By computing the CRC through hardware, the NIC can increase the performance of IP traffic and reduce CPU processing required by the protocol stack.

To avoid having the CRC computed twice (once in the hardware and again in the software by the protocol stack), make sure that your IP protocol does not compute the CRC or if it does, disable that function.

Does the 3C905B-TX NIC support NetWare versions 3.11 or 4.0x?

The 3C905B-TX does not support NetWare versions 3.11 or 4.0x. These versions require the use of a server driver that conforms to the HSM 3.2 specification. 3Com no longer develops NetWare server drivers to the HSM 3.2 specification.

What does Remote Wake-Up do? Remote Wake-Up powers up a PC remotely from

standby or suspend mode using a wake-up packet that is sent through the LAN. With this method, no one has to be at the PC to turn it on. Remote Wake-Up is also known as Wake on LAN.

How can I tell if my PC supports Remote Wake-Up?

Check to see if there is a 3-pin header for the Remote Wake-Up connector located on the PC motherboard and if your PC has a BIOS that supports wake-up events based on LAN events. If you are unsure, contact your PC vendor for further details.

What can wake up the 3C905B-TX NIC?

The NIC can be awakened by a Magic Packet wake-up packet sent by management software, or by connecting or disconnecting the TP cable.

contains a synchronization stream immediately followed by 16 repetitions of the destination MAC address. This Magic Packet is not protocol-specific as long as the protocol contains the sync stream and the 16 repetitions. This Magic Packet can be routed in order to wake up a remote PC. Since it is a valid Ethernet address, the Remote Wake-Up NIC can accept broadcast or multicast packets.

The NIC can also be awakened by connecting or disconnecting the network cable.

switched networks. Fast IP allows end systems (desktops and servers) to discover switched communication paths. By creating switched shortcuts, Fast IP allows end stations to bypass the router and transfer data across wire-speed switched paths. Fast IP is part of 3Com’s DynamicAccess software, an advanced network driver that brings intelligence to end systems to provide improved network performance and control.

Client requirements: PC running Windows 95 or Windows NT

(versions 4 or 3.51), 3Com 3C905B-TX NIC, and the TCP/IP stack

Network requirements: Switched path between stations and single

broadcast domain Fast IP is designed to bypass the router,

particularly where the router is a bottleneck, as well as to leverage the switched infrastructure. For Fast IP to create shortcuts around routers, there must be a switched path between source and destination.

Fast IP bypasses the router to provide increased performance in switched networks even if only a small number of network nodes use Fast IP. The performance gain obtained when deploying Fast IP is directly related to traffic load on the backbone router. The more traffic pumped to the router, the greater the latency and response time and the higher the performance gain. Internal tests show performance increases on the order of 600% when routers are loaded at 70 to 75%.

for the application.

The range end should be a four-digit hexadecimal number. If only one port or socket is needed, Range End should match Range Start.

4 Select the protocol that the application uses.

The protocol can be TCP, UDP, or IPX. Some applications support multiple protocols and have port or socket ranges for each protocol. In this case, the range or protocol must match the protocol on the PC.

For example, if only TCP/IP is installed, do not enter the socket range for IPX; otherwise, you could experience a decrease in performance.

5 Once the Range Start, Range End, and Protocol are

entered, click Add.

The range is added to the list. To remove a range, select the range in the list and

click Remove.
