2.2.1. Link and Activity LED: this small LED, embedded in the RJ-45 socket, glows green
when the connection is made to an active network and it blinks when any message
packets are detected
2.2.2. Collision LED: this small LED, embedded in the RJ-45 socket, blinks amber when the
LAN packets are corrupted by collisions
2.2.3. LAN Status LED: This is a two-color LED to the left of the RJ-45 connector. It shows:
−
Normal Operation : Steady green. The power supply has an active LAN connection
−
Device Identify : Blinking green. The identify function is turned on from a remote
computer using the web page or a SCPI command. The front panel blinks along with
the rear. It is used to identify one power supply in a rack of instruments. The blinking
is turned off by the web page, by sending another SCPI command, or by changing any
front panel control
−
LAN Fault : Steady red. Turns on to show the LAN connection was never made, or that
the LAN connection was made and then broken
2.3. LAN FEATURES
2.3.1. Ethernet
Meets the requirements of the IEEE 802.3u specification
2.3.2. Auto-Negotiate
May be used with 10Base-T or 100Base-T networks (10 or 100 Megabits per second). The
fastest compatible speed is automatically selected (unless disabled by the web page)
2.3.3. Auto-MDIX
Automatically detects if LAN cable is a patch (“1-to-1”) or cross-over cable. Either cable may
be used
2.3.4. MAC Address
Each power supply has a unique identifier which may be used to configure the LAN
connection. It is viewable from the supply’s front panel by holding the FOLD button. See
section 4.1 below
2.3.5. IP Address
This is the Internet Protocol address of a networked instrument. The IP addressing mode
may be set using the web page (section 5.5.2) or by the front panel LAN reset (section 4.2).
There are three modes for setting the IP address:
DHCP : The IP address is set by the network server when the power supply is first turned on
or connected
Auto-IP : If the IP address cannot be obtained from the network server, the power supply
uses an address in the range 169.254.xx.xx, where “xx” are numbers from 0 to 255
Static IP : The IP address is set by the web page and it does not change even after the
power supply is turned off and on
