3Com EtherLink II (3C503), EtherLink

II/16 (3C503-16)

Solaris Device Driver:

Device Type:

Network (Ethernet)

Adapters:

3Com EtherLink II (3C503), EtherLink II/16 (3C503-16)

Bus Type:

ISA

Connectors:

One adapter port has an RJ-45 and an AUI connector.

A second adapter port has a BNC (coax) and an AUI

connector.

Preconﬁguration Information

The 3C503 adapter uses the BNC or RJ-45 port (the non-AUI connector) as the

default if it cannot detect a device connected to the AUI connector.

Supported Settings

I/O Address IRQ

0x250–0x2E0 3

0x300–0x350 2

Known Problems and Limitations

The IRQ depends on the I/O address set using the jumpers. For example, if you

conﬁgure the 3C503 or 3C503-16 at I/O address 0x250, no other devices should

use IRQ 3.

The 3C503 board has limited on-board memory, causing poor NFS performance.

To avoid this, use a 4-Kbyte read and write buffer size to mount the NFS software

over the 3C503 interface (see mount_nfs(1M)).
