After the normal bootup and initialization (which may take several minutes), the SP’s
Good LED (green) should be on.
Installing a Redundant SP
The main SP is always installed in Slot 1. To install a redundant SP module in Slot 2:
1. Put on the antistatic wrist strap (provided in the accessory kit) and plug it into the
ESD grounding jack on the switch.
2. Use a #2 Phillips-head screwdriver to loosen the thumbscrews, then remove the
filler module from Slot 2 in the front of the switch.
3. Ensure that the ejector lock located at the top of the redundant SP module is in the
down position.
4. From the front of the switch, align the redundant SP module with the card guide in
Slot 2, and carefully slide the card into the switch.
5. Depress the card ejectors simultaneously to engage the module with the backplane
and SPA.
6. Slide the card ejector lock up.
7. Using a #2 Phillips-head screwdriver, secure the module into the chassis by
tightening the two thumbscrews (using a maximum of 6 to 8 inch-pounds of
torque).
Note – The Good and Failed LEDs on the newly installed SP blink simultaneously
while the OS software image is downloading. This is not an error condition.
Note – If the original operating system (loaded at the factory before shipping the SP)
becomes lost or corrupted, follow the instructions in the appropriate switch-code
release note to download a new OS and configuration.
Warning – The following procedure may make the device susceptible to electrostatic
charge.
