6–2 Model 2100 and 2200 Ultra SCSI Controller Enclosures User Guide
Every ECB contains a sealed, rechargeable, lead acid battery pack that can be replaced
onsite. Chapter 8 contains the procedure for replacing the battery pack.
NOTE:
The ECB battery pack is a sealed, rechargeable, lead acid battery that displays the
following label and must be recycled or disposed of properly after replacement.
Configuration
As shown in Figure 6–1, the enclosure has four ECB bays. Each array controller and cache
set within the enclosure requires an ECB. ECB bays A1 and A2 (see Figure 6–1,
3 and 4)
support Cache A. ECB bays B1 and B2 (see Figure 6–1,
1 and 2) support Cache B.
Installing an ECB in either bay (A1 or A2, B1 or B2) protects the supported cache module.
Do not install more than one ECB per array controller and cache set (A or B), except
during ECB replacement.
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 the unused ECB bays.
