DELETE A CELLWORX STN EXPANSION SHELF (EPS)
Summary: This procedure details the steps required to delete a Cellworx STN shelf that is
currently being utilized in a network as an expansion shelf (STN-EPS). The user should ensure
all connections to the EPS NE are deleted before attempting this procedure.
1. Select the NE to be deleted using the left mouse button. A white ring surrounds the NE.
2. Access the Remove EPS NE Task Overview window using the left mouse button to select
Configuration, Topology, and Remove Expansion Shelf Network Element (or using the
direct selection keys, Alt+C, Alt+T, then Alt+X). Refer to Figure 746-1.
3. The task overview window appears as shown in Figure 746-2 and the system requests
verification that this task is to be initiated. Refer to Figure 746-3. Click on Yes in the
confirmation window to continue or No to abort this procedure.
4. Step 1 indicates that the system is checking for any existing connections terminating at the
EPS. If any connections are found, the user must first delete them before continuing. Refer
to DLP-739 to delete connections.
5. Step 3 of the task overview instructs the user to reconfigure the EPS and RNE interfaces as
non-SEPIs (Shelf Expansion Interfaces). Refer to Figure 746-2. Use the following
procedures for changing the configuration on the appropriate SEPI(s):
• T3 Card Configuration DLP-753
• 155 CRS Card Configuration DLP-752
• 622 CRS Card Configuration DLP-797
6. Select the Next>> button to continue with the procedure after reconfiguring the SEPIs.
7. Step 4 of the Task Overview indicates that the system is updating the database. This will
only take a few seconds to complete. Once finished, the user is prompted to physically
disconnect the expansion shelf from the RNE. Refer to Figure 746-4. Pull the cards out of
the shelves and remove the fibers if necessary.
Danger: Do not look into the ends of optical fibers. Exposure to invisible LASER
radiation may cause serious retinal damage or even blindness. Verify the optical source is
disabled through the use of an optical power meter before handling optical fibers.
Stop! You have completed this procedure.
