antenna is not in an optimal site or there is a problem with the antenna cable connections. If
this delay is unexpected, consider relocating the GPS antenna to a better site or trouble-
shooting the GPS antenna cable.
Press the STATUS key on the front panel. The display should show “LOCKED GPS PRI” without
an asterisk (“*”). If an asterisk appears, it means that the GPS receiver is currently unlocked
from the GPS satellites, this may indicate a problem with GPS satellite visibility or signal strength.
Configuring the IEEE 1588 Card(s)
Two versions of the XLi IEEE 1588 clock are currently available:
The first version has:
An IEEE 1588 card configured as a PTP master in Option Bay 4
A GPS receiver in Option Bay 1
The second version has:
An IEEE 1588 card configured as a PTP master in Option Bay 4
An IEEE 1588 card configured as a PTP slave in Option Bay 2
A GPS receiver in Option Bay 1
Note: With two IEEE cards, be mindful of the Option Bay number when changing the settings.
PTP Master
Note: The IEEE 1588 card requires 5 minutes from power up to initialize. Until then, the card does not
appear in the user interfaces, or is reported as "NOT AVAILABLE".
Function F131 is available for configuring IEEE 1588 cards. The IEEE 1588 card located in Option Bay 4
is preconfigured as a PTP master, as shown here:
PTP AVAILABILITY - OPTION BAY 4
PTP IP ADDRESS (STATIC) - 010.048.000.103
PTP SUBNET MASK (STATIC) - 255.255.000.000
PTP DEFAULT GATEWAY (STATIC) - 010.024.000.001
PTP DHCP - ENABLE
PTP SYNC INTERVAL - 2 SECONDS
PTP BURST MODE - DISABLE
PTP PORT STATE - ENABLE
PTP SUBDOMAIN NAME - _DFLT
PTP RESET TO FACTORY DFLT? - NO
PTP INIT TO USER SETTINGS? - NO
PTP CLOCK CONFIG, BAY 1 - MASTER
