Installing a Rackmount This chapter describes the DPE installation requirements and procedures. Topics in this chapter include: • Requirements..................2-1 • Installing a DPE in a Cabinet............2-3 • DPE Powerup and Initialization ............2-16 • DPE Powerdown................2-16 • Binding Disk Modules into Groups ..........2-18 Requirements This section explains site, cabling, and addressing requirements.
Installing a Rackmount DPE remaining supply and cord support the full load. You must use a rackmount cabinet with ac power distribution, and have main branch ac distribution that can handle these values for the number of DPEs and DAEs that you will interconnect. Cooling The ambient temperature specification is measured at the front door inlet.
Installing a Rackmount DPE Loop Environments In an FC-AL environment, the DPE is addressed using the FC-AL address ID and the enclosure address (EA). Fibre Channel Arbitrated Loop Address ID (FC-AL Address ID) Each node (such as an SP) on the Fibre Channel front-end loop must have a unique Fibre Channel arbitrated loop address ID (FC-AL address ID).
Installing a Rackmount DPE You install each DPE on two L-shaped mounting rails connected to the cabinet’s vertical channels. • Installing the cabinet itself is explained in another manual. For some standard cabinets, the information is in a cabinet installation manual shipped with the cabinet. •...
Installing a Rackmount DPE 4. Open the DPE front door as shown below. If the door is locked: Latch Insert the key in the door’s latch. Turn the key 180 o clockwise. Remove the key from the latch, if desired. (If you do not remove the key, it may fall to the floor after you open the door.) To unlock, turn 180 o clockwise.
Installing a Rackmount DPE 5. Secure the DPE to the vertical channels of the cabinet as shown next. Fasten the front of the enclosure to the front channels in the cabinet using two screws (one per side). NOTE: Only one hole in the enclosure bracket aligns with a hole on the channel.
Installing a Rackmount DPE Fasten the bracket at the back of each rail to the bottom left and right of the DPE using two screws (one per side). Securing the DPE to the Cabinet Back Channel Figure 2-3 7. Close the DPE front door, as shown in Figure 2-4. The door must be closed for EMI compliance.
Installing a Rackmount DPE Raise the door until it latches into place. Latch If desired, lock the door as follows: Insert the key in the door’s latch. Turn the key 180 o counterclockwise. Remove the key, if desired. To lock, turn 180 o counterclockwise.
Page 39
Installing a Rackmount DPE 8. Perform this step only if you are installing the DPE into an FC-AL environment. Otherwise, continue to the next step. To communicate in an FC-AL environment, each SP requires a unique FC-AL address ID (the front-end address). The FC-AL protocol translates the address ID into an 8-bit arbitrated loop physical address (ALPA).
Installing a Rackmount DPE 9. For access to the ac power inlets, you must remove the drive fan pack. Remove the drive fan pack as shown below. Grasp the latches on the drive fan pack. Squeeze the latches together and pull the pack from the enclosure.

Installing a Rackmount DPE 11. Reinstall the drive fan pack on the back of the DPE. You can install the drive fan pack in either horizontal position. However, for a consistent image with DAEs, we recommend you install it with the check light in the upper right corner, as shown below.
Installing a Rackmount DPE • Avoid tight bends. If you need to make a 90º bend, do it over 6 to 12 inches. • Do not use optical cables to support weight. That includes long cable runs without support. • Do not pull long runs of cable. It is best to lay the cable in place or pull only a few feet at a time.
Installing a Rackmount DPE 13. To expand this DPE, cable its LCC EXP connector to the next corresponding DAE’s PRI (primary) connector, as shown below. Do not connect a cable between IMPORTANT: an LCC in slot A and an LCC in slot B. Plug one end of a copper cable Primary into the expansion (EXP)
Installing a Rackmount DPE DPE Powerup and Initialization The only power switches on a DPE are those on the power supply, which are normally covered by the drive fan pack. As a result, a DPE is always active. When ac power is initially applied to a DPE, the disk drives power up and spin up in a specified sequence.
Page 47
Installing a Rackmount DPE Power switches ac distribution strips SP B SP A SPS power switches 4. If the DPE has SPS protection, use the power switch on each SPS to turn off power. When you turn off power to a storage system with an SPS, the On Battery light may come on for a maximum of 90 seconds during which time the DPE will continue to run.
Installing a Rackmount DPE Binding Disk Modules into Groups After cabling a DPE and any DAEs, you can bind disk modules into groups and set up storage-system caching. To bind disk modules and set up caching, you will use a utility described in the server setup or installation manual.

Servicing and Upgrading a DPE Since you can replace or add any CRU without sliding the DPE out of the cabinet, you do not have to use cabinet anti-tip devices when you upgrade or service a DPE. If you need to power down a DPE, either: •...
Servicing and Upgrading a DPE Avoiding Electrostatic Discharge (ESD) Damage When you replace or install CRUs, you can inadvertently damage the sensitive electronic circuits in the equipment by simply touching them. Electrostatic charge that has accumulated on your body discharges through the circuits. If the air in the work area is very dry, running a humidifier in the work area will help decrease the risk of ESD damage.
Servicing and Upgrading a DPE • Before touching any CRU, touch a bare (unpainted) metal surface of the enclosure. • Before removing any CRU from its antistatic bag, place one hand firmly on a bare metal surface of the enclosure, and at the same time, pick up the CRU while it is still sealed in the antistatic bag.
Servicing and Upgrading a DPE Precautions When Handling Optical Cables When working with optical cables, observe the following precautions: • Keep the covers on all optical cables and optical GBICs until you are ready to insert the cables. The covers protect the cables and connectors, and prevent foreign particles, such as dust, from entering and affecting the connection.
Servicing and Upgrading a DPE Replacing or Adding a Disk Module CAUTION When replacing or adding a disk module, observe the following: • Remove or install disk modules only while the storage system is powered up. • Do not move a disk module that is part of an existing LUN to another slot in the storage system.
