QLogic 20-port and 10-port 4 Gb SAN Switch Modules
IBM BladeCenter at-a-glance guide
The QLogic 20-port and 10-port 4 Gb SAN Switch Modules enable high performance 4 Gb Fibre Channel
SAN solutions, and allow IBM BladeCenter integration with any open-standards-based storage area
networks utilizing full fabric switching functionality. These two switches have almost the same features
and functions except for the number of activated ports: the 10-port switch has 10 activated ports and the
20-port switch has 20 activated ports.
Figure 1 shows the QLogic 4 Gb SAN Switch Module.

Did you know?
The switch connects to the midplane directly, without having to use cables or small form-factor pluggable
(SFP) modules. By eliminating these components for up to 14 servers, the resulting savings alone cover
the BladeCenter chassis investment.
The module is licensed to operate in either full-fabric mode or intelligent pass-thru mode. The module
allows BladeCenter integration with any open-standards-based SAN, whether it is an enterprise
open-system fabric functionality using the full-fabric mode or the module with transparent switching
functionality using the intelligent pass-thru mode.


10-port licensing (10-port version only)
The switch supports the following fabric management (all management connections go through the
management module):

Management methods:


Web interface through QuickTools
Command-line interface (CLI) through Telnet program

Enterprise Fabric Suite 2007 application (for customers that already use this tool)

Switch simple network management protocol (SNMP) agent: enables a network management
workstation to receive configuration values, traffic information, and Fibre Channel failure data through
SNMP and the Ethernet interface
For the QLogic 10-Port 4 Gb SAN Switch Module, the default port license assignments are 1 through 7 for
internal ports (the first seven blade bays), and 0, 15, and 16 for external ports (the first three external
ports - see Figure 4). Port license assignments can be changed to other available internal ports (8 through
14) or external ports (17, 18, or 19) by using the QLogic management tools.

Notes:
* The 10-port 4 Gb SAN Switch Module can be installed in the BladeCenter S; however, by doing so, you
lose the ability to connect to the BladeCenter S Disk Storage Modules (DSMs). The Fibre Channel I/O
module goes in place of the SAS I/O module that is needed to connect to the DSMs.
** When the I/O module is installed in a BladeCenter T unit, the internal ports operate up to 2 Gbps, and
the external ports operate at speeds up to 4 Gbps.
† When the I/O module is installed in standard I/O bays of a BladeCenter HT unit, the internal ports
operate up to 2 Gbps, and the external ports operate at speeds up to 4 Gbps.
‡ When the I/O module is installed in an MSIM-HT, the internal ports operate at 4 Gbps, and the external
ports operate at 4 Gbps.
The BladeCenter chassis have the following bays:

BladeCenter S, E, and T have four standard I/O bays (1, 2, 3, and 4)

BladeCenter H has four standard I/O bays (1, 2, 3, and 4), two bridge bays (5 and 6), and four
high-speed bays (7, 8, 9, and 10)

BladeCenter HT has four standard I/O bays (1, 2, 3, and 4) and four high-speed bays (7, 8, 9, and 10)
The QLogic 4 Gb SAN Switch Modules fit in a standard I/O bay (bays 1-6) and, with the addition of the
Multi-Switch Interconnect Module (MSIM) in the BladeCenter H, can also fit in a high-speed I/O bay (bays
7-10). The QLogic 4 Gb SAN Switch Modules are not supported with MSIM-HT in high-speed bays of the
BladeCenter HT chassis.

The QLogic 4 Gb SAN Switch Modules support the expansion cards listed in Table 4. Table 4 also lists
the chassis bays in which the switch modules must be installed when used with each expansion card.

Note: When the I/O module is installed in a BladeCenter T chassis or in one of the standard I/O bays of a
BladeCenter HT unit , the internal ports operate up to 2 Gbps, and the external ports operate at speeds up
to 4 Gbps. When the I/O module is installed in an MSIM-HT, the internal ports operate at 4 Gbps and the
external ports operate at 4 Gbps.

Table 7 lists the LEDs on the front panel and their meanings.
Table 7. LEDs on the front panel
LED name
LED description
OK
This green LED is at the top left of the I/O module on the front panel and indicates that
the module is working properly.
! (I/O module fault)
This amber LED is at the top right of the I/O module on the front panel. This LED
indicates that the I/O module has a fault. If the I/O module fails the POST, this fault
LED is lit.
External port logged-in
(LOG)
There are six green external port logged-in (LOG) LEDs. When one of these LEDs is
lit, it indicates that there is a connection (or link) to a device on that port.
External port activity
(TX/RX)
There are six green external port activity (TX/RX) LEDs. When one of these LEDs
flashes, it indicates that data is being received or transmitted (that is, activity is
occurring) on that port. The flash frequency is proportional to the amount of traffic on
that port.
External port fault (!)
There are six amber external port fault (!) LEDs. When an external port fault LED is lit,
it indicates that the external port has failed the internal, external, or online port
diagnostics tests.
