Administrator's Guide

Table 3-3 Telnet 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.

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.
