1 Getting started The first step is to determine what type of expansion you will perform, which will determine the applicable quantity of hardware components needed.
1 Use 1 AP712A per each of the first 3 disk enclosures.

Power distribution units 0C9D Expansion rack requirements • One existing 2C18D main rack containing a properly wired controller pair and disk enclosures (see Figure 3 (page 8)). The controllers may be above or in the middle of the disk enclosures, depending on the number of disk enclosures and how the rack was initially configured. • The main rack must be running properly.

2 Installing disk enclosures into the expansion rack Before you begin Read the following warnings and cautions before installing the disk enclosure. WARNING! Make sure that the rack is sufficiently stable. If provided, lower the rack leveler feet and make sure any stabilizers are installed. If provided, extend the rack anti-tip device. Failure to extend the anti-tip device could result in personal injury or damage if the rack tips over.
1. 2. Locate the bag of eight round-hole pins included in the rail kit. Use a No. 2 Phillips screwdriver to remove the standard pins from the front and back of the left and right rails (four pins on each rail). Figure 6 Square hole to round hole cabinet conversion 3. Insert the round-hole pins into the eight holes on the rails where the standard pins were removed.
1. On the rear of the rail, squeeze the scissor latch (1, Figure 7 (page 12)) together to insert the rail and pins through the rack holes (2) until the latch engages. Figure 7 Attaching the rear rail 2. On the front of the rail, pull the locking latch to release the scissors latch (1, Figure 8 (page 12)) and then squeeze the scissor latch together to insert the rail and pins through the rack upright holes until the latch engages (3). Figure 8 Attaching the front rail 3.
Figure 9 Move retaining bracket to back 4. 5. After attaching the rail, grab and move the rail gently to be sure it is firmly engaged in the rack and that all latches are engaged in the rack holes. Repeat Step 1 through Step 4 for the other rail. Installing the disk enclosure 1. Remove the bezel covers from each side of the enclosure (see Figure 10 (page 13)). CAUTION: Be careful when removing the bezel covers so as to not break the locking tabs that secure the covers to the enclosure.
Figure 11 Slide disk enclosure onto rails 3. Continue sliding the enclosure into the rack until the front edge is flush with the front of the rack (1, Figure 12 (page 14)). Tighten the enclosure thumbscrews into the rack (2), taking care to not strip the Phillips-head thumbscrews. Figure 12 Tighten disk enclosure thumbscrews 4. 5. 14 Reattach the front bezel covers.
Figure 13 Secure rear of enclosure 6. To install disk drives: a. Insert the disk drive into the drive bay (1, Figure 14 (page 15)) until it clicks, locking the drive. b. Rotate the drive lever to the right (2, Figure 14 (page 15)) until it locks. c. Ensure the drives are installed in the proper sequence, following the numbering scheme in Figure 15 (page 15).
7. Insert a drive blank into any slot without a disk drive (Figure 16 (page 16)). Push the drive blank in until you detect a click. Figure 16 Inserting a drive blank Cabling disk enclosures in the expansion rack As in the main rack, the disk enclosures in the expansion rack should be balanced across loops — two loops for the EVA6400 and three loops for the EVA8400.

an expansion rack, there should be three disk enclosures per loop. Figure 18 (page 18) and Figure 19 (page 19) show how the disk enclosures within each loop are connected in both of these scenarios. NOTE: The numbering shown in Figure 18 (page 18) and Figure 19 (page 19) is for the physical shelf location and may not reflect the I/O module numbering. Figure 18 0C6D expansion rack for the EVA8400 1. Loop 1 2. Loop 2 3. Loop 3 For six disk enclosures in the expansion rack, complete the following steps: 1.
7. 8. 9. Power on the rack distribution units. Press and hold power push button (located at the rear of the disk enclosure) long enough to power up the disk enclosure. Repeat Step 8 for each disk enclosure in the expansion rack. Figure 19 0C9D expansion rack for the EVA8400 1. Loop 1 2. Loop 2 3. Loop 3 For nine disk enclosures in the expansion rack, complete the following steps: 1. Using 0.41m Fiber Channel copper cables, connect the disk enclosures in the first loop: a.
d. 4. 5. 6. 7. 8. 9. Connect P2 (I/O-B) on S-26 to P1 (I/O-B) on S-27. Connect the rack power distribution units to a power source. Using a power cord provided in your kit, plug one end into a disk enclosure power supply and the other end into a rack power distribution module. Plug the left power supply into the left module and the right power supply into the right module. Repeat Step 5 for each disk enclosure in the expansion rack. Power on the rack distribution units.

3 Connecting the main rack to the expansion rack You can complete the connection between the main and expansion racks while the controllers are powered on (online) or off (offline). The offline method is preferred if downtime is available. Routing cables in the expansion rack NOTE: The cables used are 5m multi-mode OM3 LC/LC fiber channel cables supplied in the AP712A kit. • Route the cables along the side of each rack so they can be secured and kept out of the way.
