The node canister battery and CMOS battery must be removed from a node canister before
you can recycle these batteries.
About this task
A small flat-blade screwdriver is required to remove the CMOS battery from its holder. Do not
remove or loosen any screws.
Before a node canister can be removed, it must be powered off or be in service state; otherwise,
loss of data or loss of access to data can result.
Use care when you remove a node canister from the enclosure. The node canister is long and its
center of gravity is far forward. It can be helpful to have a lift or other sturdy, flat surface
ready to receive the node canister during removal.
CAUTION:
The battery is a lithium ion battery. To avoid possible
explosions, do not burn. Exchange only with the approved part. Recycle or discard the battery as
instructed by local regulations. (C007a)
Procedure
Removing the node canister
Before you proceed, the customer must shut down the node or place it in service state to avoid
data loss.
Disconnect all cabling from the back of the node canister.
Locate the left and right release levers for the node canister.
On the upper node canister, the release levers are at the top of the control enclosure. For the
bottom node canister, the release levers are at the bottom of the enclosure.
Pull the left and right levers by the blue ends so that they both unlatch and swing outwards,
as shown in the following figure:
Figure 1. Removing a bottom node canister
Use the release levers to slowly pull the node canister and partially extract it from the
enclosure.
Warning: The node canister is long and heavy. You might require the use of a lifting
platform or other nearby surface to service the node canister. Observe safe handling practices as
you complete the following steps.
Hold the node canister by its sides so that it is level and its weight is balanced. Then, slide
the node canister out of the control enclosure.
Removing the cover
Place the node canister on a flat, level work surface. The release levers should be facing you
and the cover should be facing upwards.
Note: The node canister in the upper slot (node canister 1) of the control enclosure is upside-down.
To access the cover, you must turn it over after you remove it from the control enclosure.
Open the cover of the node canister. To do so, depress the recessed, blue touch points
on the lid ( 1 ) and slide the lid away from you before you lift the
cover ( 2 ), as shown in the following figure:

Set the cover aside.
Removing the node battery
Locate the node battery.
As viewed from the front of the canister, the node battery is located near the left rear
corner of the canister.
Lift the node battery latch up, as shown in the following figure:
Figure 3. Lifting the latch of the node battery
Slide the node battery toward the latch until it stops, as shown in the following figure:
Figure 4. Sliding the node battery out of its position
Lift the battery straight up to remove it from the node canister, as shown in the following
figure.

Removing the CMOS battery
Locate the CMOS battery inside the node canister.
As viewed from the front of the canister, the CMOS battery is located one-third of the way
along the right edge of the canister, next to a large black heat sink.
While avoiding contact with other components on the system board, use a flat head screwdriver
to gently release the CMOS battery from the battery holder, as shown in the following figure:

Dispose of the node battery and coin cell in compliance with local regulations.
