DLC/LLC
dlc/llc-config: (or dlc/llc:)
Enables or disables DLC/LLC protocol operation on the print server: 0 disables, 1 (default) enables.
NOTE: HP Jetdirect 635n print servers: except for TCP/IP, network protocols are disabled by factory default.
Other Settings
link-type:
(For wired 10/100/1000T Ethernet) Sets the print server's link speed (10, 100, 1000 Mbps) and communication mode (Full-
or Half-Duplex). The available link-speed selections depend on the print server model. Selections are AUTO, 1000FULL,
100AUTO, 100FULL, 100HALF, 10FULL, 10HALF.
For AUTO (default), the print server uses auto-negotiation to configure itself with the highest link speed and communication
mode allowed. If auto-negotiation fails, either 100TX HALF or 10TX HALF is set depending on the detected link speed
of the hub/switch port. (A 1000T half-duplex selection is not supported.)
upgrade:
To configure one or more Jetdirect print servers with the name and location of a firmware upgrade file.
CAUTION: Ensure that command parameters are properly entered and that the upgrade file is a higher version
than the currently installed version. The print server will attempt to upgrade when the upgrade file contains a
higher version than the installed version.
The command format is:
upgrade: <TFTP server IP> <Version> <Product Number> <Filename>
where,
<TFTP Server IP> is the IP address of the TFTP server,
<Version> specifies the firmware version of the upgrade file,
<Product Number> specifies and must match the product number of the print server,
<Filename> is the path and filename of the firmware upgrade file.
usb-mode:
Specifies the communication mode over the USB port on the HP Jetdirect print server.
●
Auto (default): Automatically negotiates and sets the the highest communication mode possible for the attached
printer or device.
●
MLC: (Multiple Logical Channels) An HP-proprietary communication mode that allows multiple channels of
simultaneous print, scan and status communications.
●
BIDIR: A standard connection that supports bi-directional communications between the printer and print server. The
print server sends print data and receives status from the printer.
●
UNIDIR: A standard connection in which data is transferred in one direction only (to the printer).
