MAP7032 Private network isolation procedure 32
The Network Topology tool has been used to determine that one or both management consoles have lost connectivity to the service processor on a single CEC enclosure (one of the two processor complexes in a storage facility) through the Black network (eth0).

Before you begin
Procedure
-
For rack model 983 only. At the front of the rack, slide the management enclosure out to the
service position and remove the top cover. See Figure 1.
Note: The management enclosure is below the two CEC enclosures.
- Fully loosen the left and right captive thumb screws.
- Slide the management out fully so the sliding rails lock into place.
- At the rear of the top cover, fully loosen the left and right captive thumb screws.
- Slide the cover back until it lifts off.
- When the service action is complete, reverse these steps.

Locate Ethernet switch SW1 (Figure 2, Figure 3, or Figure 4) in the storage facility that contains the affected service processor. Use the
tables to determine the locations of the switch port, CEC port, and Ethernet cable that correspond
to the failing service processor.
- Models 941 and 951: use Table 1 and Figure 2.
- Model 961: use Table 2 and Figure 2.
- Models 980 and 984: use Table 3 and Figure 3.
- Models 981, 985, and 986: use Table 4 and Figure 3.
- Model 982 and 988: use Table 5 and Figure 3.
- Model 983: use Table 3 and Figure 4.
