modules
All models support an optional external redundant AC power supply that can power up to four units.
The following sections describe the physical characteristics of the FastIron LS and LS-STK models.
For more details about physical dimensions, power supply specifications, and pinouts, see Chapter
7, “Hardware Specifications”.
FLS624, FLS648, FLS624-STK, FLS648-STK
FastIron LS and LS-STK devices provide high 10/100/1000 Mbps RJ45 port density and 10 Gbps
Ethernet uplinks in a compact form factor:
•The FLS624 has 20 10/100/1000 Mbps RJ45 ports and four 100/1000 SFP slots, a front
panel slot for an optional 10 Gbps CX4 module, two rear-panel 10 Gbps uplink module slots,
and a redundant power socket.
•The FLS648 has 44 10/100/1000 Mbps RJ45 ports and four 100/1000 SFP slots, two
rear-panel 10 Gbps uplink module slots, and a redundant power socket.
•The FLS624-STK has 20 10/100/1000 Mbps RJ45 ports and four 100/1000 SFP slots, one
front-panel slot for an optional 10 Gbps CX4 module, two rear-panel 10 Gbps uplink modules
and a redundant power socket.
•The FLS648-STK has 44 10/100/1000 Mbps RJ45 ports and four Gbps SFP slots, two

Control features
The front panel on each device includes the following control features:
•Serial management interface (the port labeled Console)
•Reset button
Serial management interface (Console port)
The serial management interface allows you to configure and manage the device using a
third-party terminal emulation application on a directly connected PC. A straight-through EIA or TIA
DB-9 serial cable (M or F) ships with the device. The serial management interface (the Console
port) is located in the right corner of the front panel.
Reset button
The reset button allows you to restart the system without removing power or using the CLI or Web
Management Interface. The button is located to the left of the serial management interface and is
recessed to prevent it from being pushed accidentally.
FastIron LS and LS-STK network interfaces
FLS and FLS-STK devices provide the following interfaces:
•10/100/1000 Mbps ports with RJ45 copper connectors
•100/1000 Mbps ports with mini-GBIC slots for SFP MSA-compliant fiber transceivers

•Optional 10 Gbps uplink modules (not available for FastIron LS 648-STK models)
For information about the type of fiber optic modules supported, see “Fiber optic modules” on
page 7.
FastIron LS and LS-STK 10/100/1000BASE-T ports
FLS and FLS-STK devicees contain 24 or 48 ports that operate at 10 Mbps or 100 Mbps, half or full
duplex, or at 1000 Mbps, full duplex. Because all ports on these devicees support automatic
MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or
servers, or to other devicees or hubs. (Refer to “Pinouts and signaling” on page 63.) It is best to use
MDIX cable for device-to-device connections.
Each of these ports support auto-negotiation, so the optimum transmission mode (half or full
duplex), and data rate (10, 100, or 1000 Mbps) can be selected automatically. If a device
connected to one of these ports does not support auto-negotiation, the communication mode of
that port can be configured manually.

10 Gbps Ethernet module slots for standalone devices
FLS 624 and FLS 648 standalone devices include two slots on the rear panel for single-port
10GBASE uplink modules with XFP transceivers, and a single port CX4 module. The 10GBASE
transceivers operate at 10 Gbps full duplex with support for asymmetric flow control (that is, the
port honors incoming pause frames, but does not originate pause frames).
10 Gbps Ethernet module slots for stacking devices
FLS 624-STK and FLS 648-STK devices include two 10 Gbps Ethernet CX4 modules on the rear
panel (the stacking ports). The FLS 624-STK has an additional slot on the front panel that supports
an optional 10 Gbps CX4 module.
10 Gbps CX4 ports
The single-port CX4 module is installed in the FLS 624 and FLS 648 (shown in Figure 6). You can
order the FastIron LS with a single-port CX4 module pre-installed, or you can upgrade your device at
a later time. This module is a 10 GbE-CX4 Ethernet uplink card, capable of performing data
transmission directly through copper links to 15m (extended 30m) in length.
Single-port CX4 uplink for 10 Gbps is supported.
Link and Activity LEDs on the module faceplates indicate operational status:
•If the Link LED is on, the port is connected. If the Link LED is off, no connection exists, or the
link is down.
•If the Act LED is on or blinking, traffic is being transmitted and received on the port. If the Act
LED is off, no traffic is being transmitted or received on the port.
FIGURE 6 Single-port 10 Gbps Ethernet CX4 module
Cable specifications
The following cable specifications apply to the CX4 port in the 10GbE interface module (FLS-1XGC):
•Support for 802.3ak or 10 Gbps Ethernet CX4 standard
•Support for cables up to 15m in length
•Requires latch-style receptacle or SFF-8470 plug
•Recommended CX4 cable is manufactured by WL Gore, part number IBN6600-15, CX4
Assembly - 26AWG SPC 15.0m
NOTE
The recommended CX4 cable can also be used with a Small Form Factor Pluggable (XFP)
MSA-compliant optical transceiver (part number FLS-1XGC).
Figure 7 shows the CX4-grade cable.

Fiber optic modules
A list of the types of fiber optic modules supported on Layer 2 Compact devicees can be found in
“Cable specifications” on page 64
NOTE
Some older SFP modules (mini-GBICs for Gbps Ethernet ports) have latching mechanisms that are
larger than the newer parts. These latches could interfere with one another when inserted side by
side in the same module. These older modules are identified by the number PL-XPL-00-S13-22 or
PL-XPL-00-L13-23 above the serial number. All newer mini-GBICs do not have this limitation.
DANGER
All fiber optic interfaces use Class 1 lasers.
Power supplies
There are two power receptacles on the rear panel of each device. The standard power receptacle
is for the AC power cable. The receptacle labeled “RPS” is for the optional redundant power supply.
Optional redundant power supply
The device supports an optional redundant power supply (RPS), that can supply power in the event
the internal power supply fails.

DRAFT: BROCADE CONFIDENTIAL
General requirements
To manage the system through a serial connection, you will need the following items:
•A management station, such as a PC running a terminal emulation application.
•A straight-through EIA or TIA DB-9 serial cable (F/F). The serial cable can be ordered separately
from Brocade. If you prefer build your own cable, see the pinout information in “Attaching a PC
or terminal” on page 27.
Use the serial connection to perform basic configuration tasks, including assigning an IP address
and network mask to the system. This information is required to manage the system using the Web
management interface or IronView or using the CLI through Telnet.
Summary of installation tasks
Follow the steps listed below to install your FastIron LS or LS-STK device. Details for each step are
provided in this chapter and in the following chapter.
TABLE 5 Installation tasks
Task
number
Task Where to find more information
1 Ensure that the physical environment that will host
the device has the proper cabling and ventilation.
“Preparing the installation site” on page 13
2 Install any required optional modules into the device. “Installing an optional module in the device”
on page 25
3 Install the Brocade device on a desktop, in an
equipment rack.
“Installing the device” on page 13
4 Connect stackable devices in an IronStack topology. “Connecting devices in a stack” on page 15
5 Once the device is physically installed, plug the
device into a nearby power source that adheres to
the regulatory requirements outlined in this manual.
“Powering on the system” on page 26
6 Verify that the system LEDs are registering the proper
LED state after power-on of the system.
“Verifying proper operation” on page 27
7 Attach a terminal or PC to the Brocade device. This
will enable you to configure the device through the
Command Line Interface (CLI).
“Attaching a PC or terminal” on page 27
8 No default password is assigned to the CLI. For
additional access security, assign a password.
“Assigning permanent passwords” on
page 37
9 Before attaching equipment to the device, you need
to configure an interface IP address to the subnet on
which it will be located. Initial IP address
configuration is performed using the CLI with a direct
serial connection. Subsequent IP address
configuration can be performed using the Web
management interface.
“Configuring IP addresses” on page 39
10 Once you power on the device and assign IP
addresses, the system is ready to accept network
equipment.
