Note: Contact your IBM representative for options regarding different cable and
patch panel configurations to simplify cable management with higher density
FC8-64 port blades.
Cable management recommendations:
v
Leave at least 1 m (3.28 ft) of slack for each port cable. This provides room to
remove and replace blades in the chassis, allows for inadvertent movement of
the rack, and helps prevent the cables from being bent to less than the minimum
bend radius.
v If ISL Trunking is in use, group the cables by trunking group. The ports are
color-coded to indicate which ports can be used in the same ISL Trunking group:
eight ports marked with solid black ovals alternate with eight ports marked with
oval outlines.
v
Use only hook-and-loop fasteners for securing optical cables. Do not use cable
ties. They can be easily overtightened and can damage the optical cables.
v
For easier maintenance, label the fiber optic cables and record the devices to
which they are connected.
v
Use the cable management fingers attached to the rack rails to organize the
cables off to the side of the chassis, and away from the chassis exhaust vents.
v
Keep LEDs visible by routing port cables and other cables away from the LEDs.
For the procedure to install the ICL cables see “Removing and replacing
inter-chassis link (QSFP) cables” on page 113.
Planning for encryption (optional)
Encryption is an optional feature available on the SAN768B-2 through the
installation and use of the FS8-18 encryption blade. Advance planning is essential
to achieve a successful implementation of encryption.
Attention: Setup of the FS8-18 blade for encryption requires the use of this
document for the physical installation of the blade. Critical information required
for enabling and managing encryption is contained in the
Fabric OS Encryption
Administrator’s Guide Supporting Tivoli Key Lifecycle Manager (TKLM) Environments ,
which is included on the documentation CD-ROM that is shipped with the
product. You must use both documents in order to successfully set up the switch
for encryption.
Careful attention to details of setup and configuration are essential to enabling a
secure encryption functionality. The following guidelines should be followed when
planning for encryption with the 16-port encryption blade (FS8-18), which is
available for the SAN768B, SAN768B-2, SAN384B, and SAN384B-2 products, or the
SAN32B-E4.
v
Redundancy of hardware is essential because if the encryption path is disrupted,
access to the encrypted data will be lost with a single encryption device. You
must have two encryption devices to ensure backup and access in the event that
one of the devices goes down. If one of the devices in the encryption pair is not
functioning, you will only have read access to the encrypted data on the
functioning device until the non-functioning device is restored. Redundancy of
hardware for encryption can be accomplished with the following options:
– Two Key Vault locations on different devices
– Two encryption devices in any combination of encryption switches
(SAN32B-E4) and FS8-18 encryption blades (in SAN768B, SAN768B-2,
SAN384B, or SAN384B-2 chassis)
