Ethernet TCP/IP Attachment Information

Table 20 lists all con®guration items, what each item is used for, and the allowable value options for each item. The factory-set default values are underlined.

Table 20. Ethernet TCP/IP Attachment Items

Con®guration Item	Description	Value Options
Ethernet TCP/IP	Speci®es if the Ethernet adapter is installed.	Yes or No
Installed
TCP Port	Speci®es the TCP socket address of the attachment.	5001 to 65536

	Notes:
	1. Only one address is required for operating a simplex
	system.
	2. If your installation runs in dual simplex and duplex
	mode, specify the same TCP Port value for duplex
	mode as you do for Printer 1 in dual simplex mode.
	(IBM recommends using the default value of 5001.)
	Also, make sure you specify a unique value for
	Printer 2 in simplex mode; Printer 1 and Printer 2
	cannot use the same value. (If you use the default
	value of 5001, for Printer 1, IBM recommends using
	5002 as the value for Printer 2.)
	3. The TCP Port numbers speci®ed in the printer
	con®guration must match the PORT numbers
	assigned in the host PSF system.
	4. Because Printer 1 in a dual simplex system and the
	complete system in duplex system share a common
	port number, operational procedures must be de®ned
	to distinguish between duplex and dual simplex
	printing. The easiest way to manage this is to assign
	separate queues for duplex versus dual simplex
	output (for PSF/2 and PSF/6000), and to assign at
	least a unique job class for duplex jobs (for S/390 host
	PSF systems).
IP Address	Speci®es the Internet Protocol (IP) address of the printer	X.X.X.X where X ≤ 255.
	in dotted decimal format. Get this value from your LAN
	administrator. This value must match the IP address
	value in the host PSF con®guration.
	This value is unique to a duplex system, and is the same
	regardless of whether the printer is in duplex or
	dual-simplex mode.
Subnet Mask	Speci®es the mask that identi®es the local subnet in	X.X.X.X where X ≤ 255
	dotted decimal format. Get this value from your LAN
	administrator. If you do not have a local subnet, leave
	this ®eld blank.
Default Gateway	Speci®es the IP address of the default gateway in dotted	X.X.X.X where X ≤ 255
Address	decimal format. Get this value from your LAN
	administrator.
Standard MTU Size	Speci®es the Maximum Transmission Unit (MTU) size.	60 to 1500
	The MTU size for Standard Ethernet type ranges from 60
	to 1500.
IEEE802.3 MTU Size	Speci®es the MTU size for IEEE802.3 Ethernet type. The	60 to 1492
	range is from 60 to 1492.
