Chapter 3. Cabling the storage server
This chapter provides Fibre Channel and power cabling information for the storage
server.
After you attach the storage server power cables, use the instructions that are
provided in “Turning the storage server on and off” on page 45 for the initial startup
of the storage server.
Working with SFPs and fiber-optic cables
Each RAID controller CRU contains ports for SFP modules that connect to the
fiber-optic cables. Two of the SFP ports are for host server attachment. On the
DS4300 Model 60U/60X, each RAID controller also has an additional port that
connects DS4000 EXP storage expansion enclosures to the storage server.
First, insert the SFP into the port, and then a insert a fiber-optic cable into the SFP.
The other end of the fiber-optic cable connects to an external device. Note that
SFPs are laser products.
Statement 3
CAUTION:
When laser products (such as CD-ROMs, DVD drives, fiber optic devices, or
transmitters) are installed, note the following:
v Do not remove the covers. Removing the covers of the laser product could result in
exposure to hazardous laser radiation. There are no serviceable parts inside the
device.
v Use of controls or adjustments or performance of procedures other than those
specified herein might result in hazardous radiation exposure.
Danger
Some laser products contain an embedded Class 3A or Class 3B laser diode. Note the
following.
Laser radiation when open. Do not stare into the beam, do not view directly with optical
instruments, and avoid direct exposure to the beam.
Handling fiber-optic cables
Before using fiber-optic cables, read the following precautions.
Attention: To avoid damage to the fiber-optic cables, follow these guidelines:
v Do not route the cable along a folding cable-management arm.
v
When attaching to a device on slide rails, leave enough slack in the cable so that
it does not bend to a radius of less than 38 mm (1.5 in.) when extended or
become pinched when retracted.
