ESCON Channel Configuration Information

Table 18 lists all configuration items, what each item is used for, and the allowable

value options for each item. The factory-set default values are underlined.

Table 18. ESCON Channel Attachment Items

Configuration Item

Description

Value Options

ESCON Link A

Installed

Specifies if ESCON Channel Link A is installed.

Yes or No

ESCON Link B

Installed

Specifies if ESCON Channel Link B is installed.

Yes or No

Device Address

Specifies the 2-digit hexadecimal channel address which

includes the device address.
Notes:

1.

In simplex mode, only one device address is required.

2.

In dual simplex mode, each printer requires a unique

device address. Printer 1 requires an even number

(for example, X'30'); Printer 2 requires the next

consecutive number (for example, X'31').

3.

The duplex system does not require a unique number.

It can use either of the addresses used for dual

simplex Printer 1 or dual simplex Printer 2. However,

it is often easier from an operational viewpoint to

assign duplex a separate address (so the duplex and

simplex printers look like unique devices to the

operating system). The general convention in this case

is to assign the duplex system the next consecutive

address (even) after the address for simplex Printer 2.
For example, if you define Printer 1 in dual simplex

as X'30', you should then define Printer 2 in dual

simplex as X'31', and, optionally, define the complete

system in duplex as X'32'.

4.

The device addresses specified above must match the

device addresses defined to the host PSF software,

and in the case of S/390 hosts, the I/O device

definitions.

00 to FF (Hexadecimal notation).

Default is X'00'

Multi-host

environment flag

Shows whether a multiple host printer-sharing system

exists. If this environment flag is set, all hosts are

required to use the assign/unassign protocols of the

attachment architecture. (Not supported on all printers.)

True or False
