Site Procedures for SGX 6.1.6 (Phase 2) Upgrades

SITE PREWORK:


 * Receive the boxes containing 4 disk drives, 2 CDs and these instructions.
 * Store these items until the scheduled MOP.
 * Save the shipping boxes and packing foam to return the old drives when the MOP is completed.

CO TECH MOP: (Conf Bridge: 877-533-6338, ID:  8481)


 * Call above VoIP Tier II Engineer, Eric Seligman. Eric will direct when to do all of these steps.
 * Insert one of the CDs into the CD tray of each SGX server.
 * Tier-II will then remotely shut down the first box.
 * When instructed, disconnect the serial SLAN cable and network crossover cables (1, 2, & 3 in drawing), from either of the SGXs to isolate them from each other during the upgrade.  They will remain disconnected until the second server is completed.
 * Next, disconnect the SS7 A-link cable (4a in drawing) from the server that is down
 * When instructed, remove both disk drives from the server and mark as left and right in case the MOP fails and they need to be re-inserted. (see details on page 2 if unfamiliar with this unit)
 * Install the new disks for this server in their appropriate slots. The disks are labeled for each server and the appropriate slot to install them.
 * Tier-II will remotely power up this server, then update the database.
 * Tier-II will bring down the opposite server, starting the outage. At this time you disconnect the ss7 cable (4b) and reconnect the SS7 link (4a) onto the first server.
 * Tier-II will bring up the first server, ending the outage and proceed with testing.
 * After testing the second server will be brought up and the database upgraded. When advised by Tier-II, reconnect the SS7 cable (4b) and the SLAN & network cables (1, 2 & 3).

Disk Swap Procedure - If unfamiliar with the Sun Netra 240, please read this section.

Drive Access: The front panel of the box is hinged and drops down by pulling on the two green thumb-plates. Once the front is opened, the two disk drives are accessible for removal.

Removal procedure: On the individual drive, there is a slider marked with the arrow pointing right. Slide this to the right and the removal tab pops forward. Use the tab to carefully slide the drive out of the box. Please mark the location on each drive as they are removed from the chassis. In the event the MOP fails and a back-out is required, it is critical the drives go back into the correct slot.

Disk Insertion: The replacement drives are marked with the server name and a left/right indicator. When inserting the drive there is only one correct position in the slot allowing it to seat correctly. While inserting the drive, the handle-tab must be open so press on the blue slider to push it back. Note: you may need to lift the drive slightly in order for the sliders to line up. The drive is correctly seated when it goes all the away in allowing the handle-tab to lock down in place. When correct the front of the drive will be about 1/8" behind the metal chassis face.
