4.9 SG-DRL4-2L upgrade to System 5
Customers with SG-DRL4-2L line cards can upgrade their existing cards to SG-DRL5-2L line cards by purchasing the SG-DRL5-ADPT and per-
forming a firmware update of the line card.
There are two methods to upgrade the line cards.
Method 1
If the cards are installed in the SG-System IV, they can be updated using the SG-Systems Console firmware update.
1. Select the desired line card and select the downloadable SG-DRL5 software. When the firmware update is complete, the line card can no longer
communicate with the SG-System IV receiver.
2. Convert the SG-DRL4-2L card by following the instructions below and insert the converted line card into the SG-System 5 receiver.
Method 2
1. Remove the SG-DRL4-2L card from the SG-System 5 receiver.
2. Convert the SG-DRL4-2L card by following the instructions below and insert the converted line card into the SG-System 5 receiver.
3. From the SG-System 5 console, navigate to the line code upload window and select USB upload.
4. Select the line card from the download window. When the process is complete, the line card functions in the SG-System 5.
Converting SG-DRL4-2L line cards to SG-DRL5-2L line cards
1. Connect the SG-DRL4-2L to the SG-DRL5-ADPT as shown in "FIGURE 4-16"
2. Connect the debug cable (optional) to the line card and to the SG-DRL5-ADPT (Position 1).
3. Connect the Ethernet cable to the line card and to the SG-DRL5-ADPT (Position 2).
4. Attach the plastic tie down clips in the locations shown in "FIGURE 4-16"
5. Arrange the two cables as shown in "FIGURE 4-16" and secure with the supplied zip ties. Ensure that the cables lie as flat as possible on the
circuit board to avoid becoming tangled when the line card is inserted into the SG-System 5 receiver.
