Codonics Infinity Expansion
Module Chassis Replacement
Overview
The Codonics Infinity®Expansion Module supports
customer replacement of the expansion module chassis. This
document describes the procedure for installing the
replacement chassis.
Prepare the Replacement Chassis
The new chassis will not include hard drives or power
supply modules. These components must be moved from
the failed chassis to the new chassis.
1. Unpack the Infinity Expansion Module replacement
chassis.
2. Place the replacement chassis on a flat, solid surface near
the original chassis.
3. Remove the tape securing the front cover.
The interior of the replacement chassis has four empty
hard drive slots. The hard drives and the AC power
adapter will be transferred from the failed chassis.
Shut Down the Infinity System
1. Shut down the Infinity system. Refer to “Shutting Down
and Rebooting” in the Infinity User’s Manual.
2. If there is a UPS, power it off.
3. Disconnect the AC power cord from the power outlet or
UPS.
Transfer Hard Drives
1. Open the front door of the failed chassis.
2. For each hard drive in the old chassis:
a. Open the hard drive’s lever by pulling up on the
blue tab to open the lever to about 45º.
This disconnects the hard drive from the internal
connector.
b. Slide the hard drive out of the old chassis.
c. Slide the hard drive fully into the corresponding slot
in the replacement chassis.
CAUTION: The user should be properly grounded and
observe anti-static procedures when replacing the
expansion module chassis.

CAUTION: Use care when handling hard drives. Do not
drop the hard drive. Handle only the front, side edges,
and face with the label. Do not handle the underside or
the backplane of the drive. Do not touch any exposed
electronics.

d. Close the hard drive lever to lock the drive in place.
The lever will click into position when it is fully
closed and locked.
Connect Power Adapter and SAS
Cables
1. Release the retaining clip and disconnect the power
adapter’s connector from the power plug on the rear of
the failed chassis.
2. Connect the power cord to the power connector on the
rear of the replacement chassis.
3. Secure the power cord with the retaining clip.
4. Disconnect the SAS cable(s) from the rear of the failed
chassis and connect them to the corresponding IN and
OUT connectors of the replacement chassis.
The first figure below shows the SAS cable connection
(the gray cable) from the main chassis’ SAS connector to
the first expansion module’s SAS IN connector. The
second figure below shows the SAS cable connections
between the SAS OUT connector of an expansion module
to the SAS IN connector of the next expansion module in
the chain.
Power On and Start Up the System
1. Plug the AC power cord into the power outlet or UPS.
2. Momentarily press the Power button at the front of the
Infinity main chassis to start up the system.

CAUTION: When installing the hard drive, it is
important to insert it all the way into its slot. Push the
drive as far into the slot as it will go (it should be flush
with the neighboring drives). There is some resistance
when the back of the drive is seated in the cage. It is
possible to latch the lever without having the drive fully
installed. It is critical that all drives are properly
installed prior to the initial system startup of the
replacement chassis.
CAUTION: Make sure that each hard drive is installed
in the corresponding slot in the replacement chassis.
