To get the microcode from the BBS:
1
Prepare your computer to call the IBM Bulletin Board System.
You need a computer with a modem and communications software in order to
make the call. Make sure that your communications software is set to use 8
data bits, no parity, 1 stop bit, and no flow control.
2
Dial one of the following numbers:
United States
(919) 517-0001
Toronto
(905) 316-4255, (416) 956-7877

Management Using Telnet
You can access your 8237 using Telnet, either in-band, over an Ethernet connection
or out-of-band, using SLIP.
When you connect using Telnet, you will see the user interface that has already
been documented in this chapter.
Configuring for SLIP
The 8237 management unit supports two IP addresses, one for Ethernet and one for
the serial line. When configuring your 8237, these addresses are entered on the
Segment Configuration panel (see Figure 3-10 on page 3-13) in the IP Address and
Serial IP fields, respectively. Both of these addresses share a common subnet
mask. In order for SLIP to function, both IP addresses must be on the same
network. If the subnet mask is
255.255.255.0
, you might configure the two
addresses
9.123.1.9
(Ethernet IP address) and
9.123.1.10
(serial line IP
address). If the addresses are on the same network, the first three portions of the IP
address must be identical.
Another requirement is that the SLIP client/host (the PC or device that is connected
to the 8237 by a serial link) must use the same IP address and subnet mask as the
8237 Serial Line IP. Using the above example, the address and subnet mask for the
SLIP client/host must be
9.123.1.10
and
255.255.255.0
, respectively.
