HP 640n Print Server manual Wireless 802.11 Main

Table 3-3Telnet Commands and Parameters (continued)

passwd	Password that allows administrators to control changes of HP Jetdirect print server
	configuration parameters using Telnet, the HP Embedded Web Server, or HP Web
	Jetadmin. For example, passwd jd1234 jd1234 sets the password to jd1234. (You
	must enter the password jd1234 twice for confirmation.)
	Enter up to 16 alphanumeric characters. Clear the password using a cold reset or enter
	the command without a password and confirmation entry.
sys-location	Physical location of the device. Enter up to 255 alphanumeric characters.
sys-contact	Name of the network or device administrator. Enter up to 255 alphanumeric characters.
ssl-state	Print server's security level for Web communications, using the following values:
	1: Enable forced redirection to the HTTPS port. Use only HTTPS (secure HTTP)
	communications.
	2: Disable forced redirection to HTTPS. Use both HTTP and HTTPS communications.
security-reset	Reset security settings on the print server to factory default values.
	0 (default): Do not reset.
	1: Reset.
Wireless 802.11 Main
Wireless Mode	802.11 wireless mode.
	B/G_MODE: Use 802.11b or g.
	B/G/N_MODE (default): Use 802.11b, g, or n.
Guard Interval	The space between transmitted symbols (characters). Can eliminate inter-symbol
	interference (ISI), which occurs when echoes or reflections from one symbol interfere
	with another. A long interval can reduce echoes, but decrease the data rate. A short
	interval can increase the data rate by approximately 10 percent.
	AUTO (default): Automatically set the guard interval based on the wireless mode.
	SHORT: Set to short interval (400 ns).
	LONG: Set to a long interval (800 ns).
AMSDU Aggregation	Aggregating 802.11n MAC service data units packs them into frames to reduce
	overhead and increase the data rate. Enabling aggregation allows a maximum frame
	size of 7935 bytes.
	ENABLE (default): Enable aggregation.
	DISABLE: Disable aggregation.
Block ACKs	Use block acknowledgement of AMPDUs.
	This mechanism allows each of the aggregated data frames to be individually
	acknowledged or retransmitted if affected by an error. (Automatically enabled when
	AMPDU Aggregation is enabled.)
	ENABLE (default): Enable AMPDU block acknowledgements.
	DISABLE: Disable AMPDU block acknowledgements.
