1) Power LED. Lights when the module has power.
2) Module OK LED. Lights when the module passes self-
test. Flashes when a non-fatal error occurs on self-test.
If the module fails self-test, the Module OK LED is off.
3) Network Traffic. Flashes or remains on depending on
network activity.
4) Network OK. Lights when the module has an active net-
work connection.
5) Seven-Segment Display. Provides error and status

Obtaining RFCs and Digital Private MIBs: Using ftp
You can obtain Requests for Comments (RFCs) and up-to-date DEChub Management Information
Base (MIBs) from Digital using anonymous ftp.
Digital offers Internet anonymous ftp access to private MIB information, in ASCII text
form, at GATEKEEPER.DEC.COM, with up-to-date documents stored in the directory
/private/mib. Check the index file and the reamdme file for the current contents. To
use anonymous ftp to copy files, follow these instructions:
1. Use the Internet application ftp to connect to gatekeeper.dec.com (the Internet
address is 16.1.0.2).
2. Log in as user anonymous.
3. Use your electronic mail address as the password.
4. Use the cd command to get to the directory /private/mib
5. Use the ascii command to specify that you are retrieving ASCII text files.
6. Use the get command to get the file or files that you require.
7. When you are finished, use the quit command to log out.
Note that user input is case sensitive; you must type it as shown (user input is shown in
boldface type).
Here is an example of copying the readme file from the repository.
