xDirect User Guide 56

Increasing CPU clock speed consumes more power and generates more heat. This reduces

the maximum operating temperature specification. See the appropriate product brief for

details.

Monitor Mode at Bootup

This option allows you to disable all entries into Monitor Mode during startup, except for the ‘xxx’

sequence. This prevents entry using yyy, zzz, xx1, and yy1 key sequences (only during the

bootup sequence). The default for disabling Monitor Mode at bootup is N (No). See Chapter 11:

Monitor Mode.

Disable Monitor Mode @ bootup (N) ?

HTTP Port Number

This option allows the configuration of the web server port number. The valid range is 1-65535.

The default HTTP port number is 80.

HTTP Port Number : (80) ?

MTU Size

The Maximum Transmission Unit (MTU) is the largest physical packet size a network can transmit

for TCP and UDP. Enter between 512 and 1400 bytes. The default setting is 1400 bytes.

MTU Size (512 - 1400): (1400) ?

TCP Re-Transmission Timeout

This feature allows the configuration of the desired TCP re-transmission timeout value. If the ACK

is not received for a packet sent from the xDirect device, then the unit will retransmit the data. The

valid range is 500-4000 msec. Default is 500.

TCP Re-transmission Timeout (500 - 4000) (ms): (500) ?

Enable Alternate MAC

If necessary, enable the alternate MAC address (if specified in the OEM setup record). The default

setting is N (No).

Ethernet Connection Type

The xDirect allows for the Ethernet speed and duplex to be manually configured. Enter 0 for auto-

negotiation (default). To select the speed and duplex, enter one of the following: 2 (10Mbit/half

duplex), 3 (10Mbit/full duplex), 4 (100Mbit/half duplex), or 5 (100Mbit/full duplex).

Ethernet connection type: (0) ?

Security Settings (Option 6)

You can change security settings by means of Telnet or serial connections only, not on the Web

Manager. We recommend that you set security over the dedicated network or over the serial setup

to prevent eavesdropping.
