Danger of electrostatic discharge! Static electricity can harm delicate components inside the Shelf. An ESD wrist strap must be worn before exchanging any part or electric component! The ESD Wrist Strap Terminal (4 mm banana jack) is located at the upper front side of the Shelf. |
1. To insert the blades – engage the “hooks” on both handles, and rotate both handles simultaneously towards the face of the blade to force the blade back into the chassis.
2. Secure blade by tightening screws top and bottom.
3. Pinch the spring lever to raise the finger and push hot swap handle home through the faceplate. Release the spring lever to lower and retain the handle. Failure to do this will erode the plastic and permit the handle to release easily.
Note: GPS 10M and 1Hz connections. The 10M and 1Hz should not be removed from a live system. If the primary or secondary GPS SDRs are to be removed the hot swap handle on the SDR should be activated, once the blue light is on (not flashing) the GPS cables can be removed.
1. When a card is to be replaced, release the hot swap handle by rotating the upper part of the handle to the position shown in Figure 2 below.
Figure 1: Hot Swap Handle: Normal
Figure 2: Hot Swap Handle: Released (Hot Swap Initiated)
2. The H/S blue light flashes – when it stops flashing and is permanently on the board can be removed by unscrewing the top and bottom screws and rotating both upper and lower handles forward to disengage card.
