DLP-U361 Downgrade the SSXC Card to the CXC Card

Warning

Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed
circuitry could constitute an energy hazard.

Warning

Before contacting a shelf or card(s), ensure that you are wearing appropriate anti-static devices
(wrist straps or foot straps).

Note

Card removal raises an improper removal (IMPROPRMVL) alarm, but this clears after the card
replacement is complete.

Step 1

If CTC is not started, start CTC.

Step 2

Verify that there are no critical alarms in the network.

Step 3

In node view, click the Maintenance tab and click the Preferred Copy button.

Step 4

View the preferred data copy currently in use (A or B) and verify that all traffic is using that copy (the
Currently used Data Copy field should show the same copy).

Step 5

Physically remove the nonpreferred SSXC (for example, if the preferred copy is A, remove SSXC B):

Open the card ejectors.

Slide the card out of the slot.

Note

An UNPROT-SCMTX alarm is reported when you remove the SSXC card.

Step 6

Install the replacement CXC card in the shelf:

Open the ejectors on the replacement card.

Slide the replacement card into the slot along the guide rails until it contacts the backplane.

Purpose

This task downgrades the SSXC card to the CXC card in the case where
a software revert must be performed from Software R8.0 to
Software R1.4. The SSXC card supports Software R8.0. The CXC card
