Chapter 12 Installing, Removing, and Replacing
Tape Drive Ethernet Connectivity and the Ethernet Expansion Blade
Scalar i500 User’s Guide 466
• You may not connect a tape drive to both an Ethernet Expansion
blade and an FC I/O blade.
• You are limited to a maximum of four blades per library (Ethernet
Expansion blades and FC I/O blades), in any combination.
• If the tape drive Ethernet connection or an Ethernet Expansion blade
fails, you will not be able to perform encryption operations on any
connected tape drives that have FIPS mode enabled. You will still be
able to collect tape drive logs and update tape drive firmware via
internal serial communication.
Cabling a 5U Library for
Ethernet Connectivity 12
In a 5U library:
1 Upgrade library firmware to version 600G or later.
2 Upgrade tape drive firmware on all HP LTO-5 FC or HP LTO-6 FC
tape drives that you plan to connect via Ethernet to the latest version
qualified with the Scalar i500 library (see the Scalar i500 Release Notes
for qualified firmware levels).
3 Shut down the library.
4 Connect the tape drives to one of the four internal Ethernet ports on
the library control blade (LCB) using Ethernet cables (see Figure 63
).
5 Power on the library.
Caution: If the Ethernet Expansion blade or Ethernet connectivity
fails and the attached tape drives have FIPS mode
enabled, all encryption operations (encrypting,
decrypting, key requests) on the attached tape drives will
fail. These operations will NOT automatically continue
over internal serial communication. If this happens,
contact Quantum Support for a replacement Ethernet
Expansion blade as soon as possible.
Note: This figure and subsequent figures show two cables, but
only one cable is used unless you are using data path
failover.
