DISPATCH INSTRUCTIONS
   WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED: An understanding of Guided Maintenance in R4 and R5
   TIME ESTIMATE: 30 minutes
   TASK COMPLEXITY: 0

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:
   PROBLEM OVERVIEW: An SFP has failed in an Axiom.
   WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?: The SFP can be in Failed/Warning status.
   WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE: Replace the SFP module.

NOTE: Please refer to Document 1535352.1 Pillar Axiom: How to Disable Call Home to Prevent Automatic Service Request ASR Generation before proceeding with the procedure below. The steps contained therein are provided to allow an Administrator to de-activate a particular ASR enabled array while performing maintenance or troubleshooting. This will prevent any additional Service Requests from being created unnecessarily.

PLEASE READ THE FOLLOWING NOTICES BEFORE DRIVE REPLACEMENT

Small Form Factor Pluggable (SFP) module replacement disrupts access over the optical fiber that connects to this module. However, if this module is the only failure point and the system is cabled to the customer switches in the manner that we recommend, access to data is not disrupted during the procedure to replace the SFP module.
Optical fiber-based Network Interface Modules (NIM) support the following types of connectors:
● NAS SFP modules
● SAN SFP modules

SFP Plus connectors are used with the 10 Gb/s Ethernet connections in optical NAS Slammers, while the SFP connectors are used with optical 8 Gb/s Fibre Channel (FC). Passive copper cables, for copper 10 Gb/s NAS Slammers, are available with the SFP Plus module attached to each end of the cable.

Important! Pillar Axiom 600 offers a set of qualified SFP modules for version 2 PIMs, version 2 SATA RAID controllers, and version 2 FC RAID controllers.

Access SFP modules from the back of the Slammer chassis. A Slammer Control Unit (CU) has a pair of SFP modules located within the CU NIM. You need to identify related CU and NIM via using Guided maintenance.

Remove an SFP Module

There is no Guided Maintenance for SFP module replacement.

1- If multipathing is Not implemented at host side and the path needs SFP replacement is the only active path for hosts then quiesce required on all NAS or SAN host activity over this data path. If multipathing is implemented at host side and hosts can use alternate paths while maintenance activity performed on path requires SFP replacement there is no need to quiesce host activity.

2- Ensure the fiber optic cable that is connected to the SFP module is labeled so you can correctly reconnect the cable later.

3- Press down on the locking tab on the top of the fiber optic cable with your thumb and gently detach the fiber optic cable from the SFP module.

4- Set the cable aside.

5- Pull the latch handle on the SFP module down until the latch stops.

6- Extract the SFP module.

Important! Please wait at least one minute before doing any action after removing the SFP from port to give enough time to active FC components to update port status correctly.

Insert an SFP Module

There is no Guided Maintenance for inserting an SFP module.

1- If you have not already done so, put on an antistatic wrist strap.

2- Remove any dust covers from the SFP module.

3- Gently slide the SFP module into the appropriate optical port and press it inwards until the latching mechanism is fully seated in place with a clicking sound.

Insert the notch on the SFP module face down into the FS ports located in the top row of the private interconnect module (PIM).
Insert the notch on the SFP module face down into the FC ports located in the bottom row of the PIM.
Insert the notch on the SFP face down in the FC ports located in the version 2 Brick RAID controllers.
Insert the notch on the SFP module face up into the FS ports located in the bottom row of the PIM.

Important! Make sure the SFP transceiver or plug is fully inserted and engaged into the slot. Latch releases must be in the closed and latched position before inserting the SFP transceiver or plug into the SFP cannister.

4- With the locking tab on the fiber optic cable facing up, insert the fiber cable into the replacement SFP module.

5- Push the fiber cable firmly into place until the locking tab snaps shut.

6- Check that the LED next to the network port containing the SFP module shows green.

7- Inform NAS or SAN clients to reestablish their storage connections.
