If the “Remote” LED responded as expected, the shelf is now properly
configured.
N
OTE
: It is expected that this same LED can illuminate during
main shelf operation. This occurs if the DS1-4 input has been
enabled, the input has been qualified, and is being used as the
active timing reference. In such a case all three LEDs in the
DS1-4 row are illuminated, so it is easy to to distinguish this
main shelf operating mode from the use of the “Remote” LED
as an indicator that the shelf is configured for Remote. When
indicating Remote operation, the “E” and “Q” LEDs in the DS1-
4 row will never be lit.
NOTE
: Remote shelf capability is not supported in management
(090-55542-01) and clock (090-55512-0x, 090-55514-0x) cards
having firmware versions 4109x. The firmware version of each
card can be retrieved via the TL1 RTRV-NETYPE-ALL
command, which inventories the shelf contents. (See TimeHub
5500 TL1 Reference Manual for detailed information about this
command.) If you have any of these firmware versions in your
management or clock cards and are interested in remote shelf
operation, contact the Symmetricom CAC for information about
firmware upgrades.
