HP ESL E-series Tape Libraries - Manual (Page 18)

Switch for the internal network
CAUTION:
Do not connect this switch to your local LAN. It is for internal library use only. Connecting this switch to
the LAN could cause library components to perform incorrectly or report failures.
The 24-port Ethernet switch provides a private management network to connect the Interface Manager
card to the LTO4 tape drives. You must install one switch in each library that contains LTO4 tape drives.
The ESL library uses a ProCurve Switch 2124. This switch has 24 auto-sensing 10/100Base-TX RJ-45
ports. This switch is a store-and-forward device that offers low latency for high-speed networking.
The switch does not have a power switch; it is powered on when connected to an active AC power
source. The switch automatically adjusts to any voltage between 100-240 volts and either 50 or 60 Hz.
There are no voltage range settings required. The reset button is used to reset the switch while it is
powered on. This action executes the self test, and may clear certain error conditions that have occurred.

Tape drives
The ESL E-Series tape library can hold up to 24 tape drives. When fewer than 24 drives are installed in
the library, the tape drives must occupy consecutive drive clusters, beginning with drive cluster 0 (see
Figure 2 ).
CAUTION:
It is critical to ensure that the media you use matches the format of your tape drive. Cleaning cartridges
and formatted data cartridges are unique for each drive technology. Damage may occur if inappropriate
media is used in tape drives.
Tape cartridges and cleaning cartridges are not included with the library, and must be ordered in
addition to the library.
Cleaning cartridges
NOTE:
By default, Autoclean is disabled. Ensure your application software supports this feature before enabling
it.
If a drive experiences read/write errors when the Autoclean function is enabled, the library issues an
error message stating that drive cleaning is required. Without user intervention, the media picker replaces
