Chapter 5: Subsystem Maintenance and Upgrading
Do not disassemble or modify the BBU. If disassembled, the
BBU could leak acid, overheat, emit smoke, burst and/or ignite.
Do not pierce the BBU with a sharp object, strike it with a
hammer, step on it, or throw it. These actions could damage or
deform it and internal short-circuiting can occur, possibly will
cause functional defects, acid leak, and other hazardous results.
If a BBU leaks, gives off a bad odor, generates heat, becomes
discolored or deformed, or in any way appears abnormal during
use, recharging or storage, immediately remove it from the
subsystem and stop using it. If this is discovered when you first
use the BBU, return it to Infortrend or your subsystem vendor.
To replace a BBU, please follow these steps:
Step 1.
Remove the faulty unit from the chassis
by using a
medium-size Phillips screwdriver to loosen the retention
screw, then pulling out the BBU. (See
Figure 5-6
)
Figure 5-6: Removing the BBU
Step 2.
Install the Replacement BBU.
Align the BBU with the
module slot, and then gently push the BBU into the slot.
When you feel the contact resistance, use slightly more
force for the back-end connector to mate with the
backplane.
Step 3.
Secure the BBU to the subsystem
by fastening the
retention screw. (See
Figure 5-7
)
