Configuring a Point-to-Point Link for Test Testing the Components

To have each log in the BHM correlated to a meaningful time and date, either a reliable network
element must pass time and date to the BHM or you must set the time and date whenever a power
cycle of the BHM has occurred. A network element passes time and date in any of the following
scenarios:
• A connected CMM2 passes time and date (GPS time and date, if received).
• A connected CMMmicro passes the time and date (GPS time and date, if received), but only if
the CMMmicro is operating on CMMmicro Release 2.1 or later release. (These releases
include an NTP server functionality.)
• A separate NTP server is addressable from the BHM.
If the BHM should derive time and date from either a CMMmicro or a separate NTP server, enter
the IP address of the CMMmicro or NTP server on this tab. To force the BHM to derive time and
date before the first (or next) 15-minute interval query of the NTP server, click Get Time through
NTP.
If you enter a time and date, the format for entry is
Time :
hh
/
mm
/
ss
Date :
MM
/
dd
/
yyyy
where
hh
represents the two-digit hour in the range 00 to 24
mm
represents the two-digit minute
ss
represents the two-digit second
MM
represents the two-digit month
dd
represents the two-digit day
yyyy
represents the four-digit year
Proceed with the test setup as follows.
Procedure 14: Setting up the BHS for test
1. Enter the appropriate information in the format shown above.
2. Click the Set Time and Date button.
NOTE: The time displayed at the top of this page is static unless your browser is
set to automatically refresh.
3. In one hand, securely hold the top (larger shell) of the BH that you intend to
deploy as a timing slave. With the other hand, depress the lever in the back of
the base cover (smaller shell). Remove the base cover.
4. Plug one end of a CAT 5 Ethernet cable into the BHS.
5. Plug the other end of the Ethernet cable into the jack in the pig tail that hangs
from the power supply.
6. Roughly aim the BHS toward the BHM.
