Problem Solution
Supervisor fails to operate or power up
1. Ensure that the card is inserted firmly in the slot.
2. Ensure that you have place the gold edge of the PCB in the guide rails of the
chassis. This prevents damage to the connector placed at the rear side the
board.
3. Check whether the ejector levers are latched and that the captive screws are
fastened properly. If you are uncertain, unlatch the levers, loosen the screws,
and attempt to reset the supervisor again.
4. Examine the power supply to see whether the chassis, as a whole, is
receiving power.
5. Use the status LED on the supervisor to verify the correct installation of the
card. If the card is properly installed, the status LED turns green.
Note If the system is running on reduced DC power supply, the system LED
on a supervisor turns to orange from green. In this scenario, the system
can run, however, not all the modules in the chassis may be supported.
Supervisor dual in-line memory module
(DIMM) detection issue
1. Ensure that you have correctly installed DIMM in slot 1.
2. Ensure that you follow the standard ESD procedures while upgrading or
replacing DIMMs.
RSP720 DIMM upgrade issues
1. Ensure that you remove the existing DIMM from slot 1.
2. Ensure that both the slot 1 and slot 2 DIMMs are from same vendor.
3. If you are upgrading the RP DIMMs to 2 Gigabytes by adding an extra
Gigabyte DIMM in slot two, ensure that you insert the both the new 2
DIMMs in slot 1 and slot 2.
4. If you insert the DIMMs in both the slots for RP upgrade, and card does not
initiate, then swap the DIMMs between the two slots and check again.
