PS6000 Hardware Maintenance

You may need to temporarily remove a control module to replace a micro SD

card.

Notes: For proper cooling, do not leave a control module slot empty. If an array

will operate for a long time with only one control module, you must

install a blank control module in the empty slot. You can order a blank

control module from your PS Series array service provider.

If you remove the active control module, there will be a short interruption

as failover to the secondary control module occurs.

You can partially or completely remove a control module without shutting down

the array if the remaining control module has at least one connected and

functioning network interface. If you remove the active control module (the LED

labeled ACT will be green), there will be a short interruption as failover to the

secondary control module occurs.

Otherwise, if possible, cleanly shut down the array before removing the module,

as described in Shutting Down and Restarting an Array on page 1-5.

Caution:

Do not remove a control module from an array while the control

modules are still synchronizing. A message will appear on the

console when synchronization completes. The ACT LED on the

secondary control module will be orange when synchronization

completes.

Before removing a control module:

•

Attach an electrostatic wrist strap, as described in Using an Electrostatic Wrist

Strap on page 1-5.

•

Disconnect any serial or network cables attached to the control module.

Optionally, re-attach the network cables to the functioning control module to

provide uninterrupted data access.

To remove a control module:

1. Open the control module latches by squeezing together the release mechanism

for each latch and then rotating each latch outwards.This will disengage the

control module from the array. See Figure 3-4.
