Basic DS33ZH11 Initialization
This section covers the EEPROM methods for configuring the DS33ZH11.
1) If the HWMODE jumper is installed, the DS33ZH11 will retrieve configuration settings from the on-board
EEPROM during power-up.
2) Select which serial device to use: either the DS3150 T3E3 LIU or the DS21348 T1E1 LIU can be selected. In
making this selection the backplane jumpers JP05–JP08 must be installed to select between the two serial
devices. Connecting pins 2+3 of each jumper selects the DS3150, connecting pins 1+2 of each jumper selects
the DS21348.
3) Configure the serial device as shown in Table 2 .
Additional Configuration for DS33ZH11

Using a patch cable, connect the Ethernet connector to an ordinary PC, or network test equipment. This should
cause the link LED to turn on.
Place a loopback connector at the network side; the RLOS LED should go out. The RLOS LED is DS15 for
T1E1 and DS13 for T3E3.
At this point any packets sent to the DS33ZH11 are echoed back. Incoming packets (i.e., ping) should cause
the RX LED to blink, after which the TX LED should also blink.
Monitor and Capture Ethernet Traffic

Although ping is mentioned, it is not recommended. The ping command goes through the computer’s TCPIP
stack, and sometimes is not sent out the PC’s network connector (i.e., if the PC’s ARP cache is out of date).
Additionally, ping requires two PCs, as a PC with only one adapter cannot ping itself (a local ping gets sent to a
local host instead of out the connector). However, note that ping is still a valuable test once the prototyping
stage is complete.
Generation and capture of arbitrary (raw) packets can be accomplished using CommView. A time-limited demo
is available at the website www.tamos.com/products/commview .
Ethereal is an excellent (and free) packet capture utility. Download at www.ethereal.com .
Adding additional Ethernet ports to a PC is rather simple when a USB-to-Ethernet adapter is used. This allows
for end-to-end testing using a single PC. When using two adapters, the PC has a different IP address for each
adapter. Test equipment allows selection of either adapter. Operating system-based network traffic is sent out
the default adapter. Typically, this is the adapter that has recently had connection to a live network.
