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.
