8–12 Model 2100 and 2200 Ultra SCSI Controller Enclosures User Guide
Replacing an ECB
For array controller configurations with FRUTIL support, follow pluggable procedures;
otherwise, follow hot-pluggable procedures. See Figure 8–7 for ECB bay locations.
Figure 8–7. ECB bay locations
Pluggable procedures use FRUTIL to update the ECB battery’s expiration date and deep
discharge history.
Hot-pluggable procedures only replace the ECB using a vacant bay opening (A or B) that
correlates with the defective ECB. This method does not update ECB battery history data.
This procedure installs the replacement ECB and then removes the defective ECB.
Refer to Figure 8–8 as needed during the removal and installation. Complete the
procedure in Table 8–9 to install an ECB. Complete the procedure in Table 8–10 to
remove an ECB.
NOTE:
No more than two ECBs are supported within the enclosure at any time—one for each
array controller and cache set. Install blanks in remaining vacant ECB bays to control air flow.
