HP StorageWorks e2400-FC 4G Interface Controller User and Service Guide (December 2005)

Introduction10
• Reset hole—forces a manual reboot of the FC interface controller. Use a pen or paper clip to
press the button (located behind the hole).
CAUTION: Rebooting the controller during an ongoing data backup, restore, or other data transfer
process can result in a disruption of that process and a loss of data. Before pressing the Reset
button, visually inspect the activity LEDs of all I/O ports on the FC interface controller to verify that
no data is being transferred.
• Power LED
• Green indicates that power is applied to the controller.
• Amber indicates that the Power-On Self-Test (POST) is in progress, or a fault condition has
been detected. It is normal for this indicator to flash when the controller is powered up or
reset. If the fault indicator stays lit, contact your product support representative.
• Serial port—The e2400-FC 4G is equipped with one serial port. The serial port is an HP service
port and is not intended for customer use.
• Ethernet port—The e2400-FC 4G has one 10/100BaseT Ethernet connection that is used for
management and configuration by the HP StorageWorks Interface Manager card. The Ethernet
port has two LEDs:
• Green Link LED (right) indicates a valid Ethernet link.
• Green Activity LED (left) indicates Ethernet port activity.
• Internal and external FC ports—The e2400-FC 4G has two FC ports (FC0 and FC1) for
connecting to the SAN, and four FC ports (TD0—TD3) for connecting to tape drives inside the
library. Each FC port has two corresponding LEDs:
• Green Link LED (LINK) indicates a valid FC link.
• Green Activity LED (ACT) indicates FC port activity.
Typical installations will have the FC interface controller connected to either arbitrated loop or
switched fabric environments. For an arbitrated loop, the unit can be directly attached to the FC
host bus adapter (HBA).
• Beacon—The beacon LED is used for unit identification.
Functional overview
ESL E-Series libraries contain a private LAN internal to the library. The library cabinet controller
provides a bridge between the external LAN and the library internal LAN and Interface Manager
card.
With the EML E-Series tape libraries, the external LAN communicates directly to the Interface
Manager card using the card’s network IP address. The Interface Manager card processes requests
and relays information to the Fibre Channel (FC) interface controllers. The robotics controller is
connected directly to the Interface Manager card through an Ethernet connection.
Figure 2 and Figure 3 show how the different user interfaces communicate with the Interface
Manager card in the ESL and EML libraries respectively.
