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 m anagem ent network to connect the Interface Mana ger
card to the LTO4 tape drives. You must install one switch in each library that contains LTO4 tape d rives.
This switch is a store-and-forward device that offers low latency for high-speed networking.
The EML library uses a ProCurve Switch 1700-24. This switch has 22 auto-sensing 10/100Base-TX RJ-45
ports and two dual-personality ports (ports 23 and 24). Because the RJ-45 ports support automatic
MDI/MD I-X operation, you can use straight-through cables for all network c onnections.
Dual-personality ports use either the 10/100/1000Base-T RJ-45 connector, or a supported ProCurve
mini-GBIC for fiber-optic connections. By default, the RJ-45 connectors are enabled.
The features of the Procurve Switch 1700-24 include the following.
