InfiniBand Blade Switch for the Dell Modular Server Chassis
This document provides instructions on how to install the Cisco M SFS7000E InfiniBand Switch in the Dell Modular Server Chassis. The Dell Modular Server Chassis is a system that supports up to sixteen server modules and up to four InfiniBand switches. You may install the InfiniBand switch in one of four chassis I/O module bays on the rear panel of the server chassis.
Note There are six chassis I/O module bays on the rear panel of the server chassis. The InfiniBand switches are supported in the middle four bays that are connected to Fabrics B and C.
For details about the number, types, and location of the module bays and for additional information about the entire modular server system, see the documentation for the Dell PowerEdge Servers at www.support.dell.com.

Switch Description
This section describes the Cisco M SFS7000E InfiniBand Switch.
The Cisco M SFS7000E InfiniBand Switch (see Figure 1) connects to the mid-plane of the Dell Modular Server Chassis and provides user-accessible rear-plane ports. The blade switches are installed in the system I/O module bays in the rear of the chassis. Each switch has sixteen 4x ports facing the mid-plane and eight 4x ports facing the exterior of the chassis. These ports drive Cisco- or Dell-approved DDR IB cables.
Figure 1 Cisco M SFS7000E InfiniBand Switch
I/O Module Bays and HCA Expansion Cards
Within the Dell Modular Server Chassis unit, blade switches manage traffic to and from up to two HCA IB mezzanine cards on the hosts. Each HCA IB mezzanine card adds two IB ports to a host. Each HCA port connects through the unit mid-plane to a particular blade switch slot. The IB ports of the HCA card that is seated in the HCA B location, connect to I/O module bays B1 and B2. The IB ports of the HCA card that is seated in the HCA C location, connect to I/O module bays C1 and C2. See Figure 2 and Table 1 for the location of the HCA cards and the corresponding I/O module bays.
For more details about the location of the HCA IB mezzanine card slots in the Dell Server Blade, see the Dell PowerEdge M600 and M605 Hardware Owners Manual.

Pre-installation Guidelines
This section describes some pre-installation guidelines. Before you begin installation, complete the following procedures:
•Ground yourself using an approved ground wrist strap.
•Make sure that you have the correct cables.
•Unpack the Cisco M SFS7000E InfiniBand Switch. Remove the packaging from around the switch. Do not cut the packaging, as you could damage the switch. Save the box and packaging.
Note If you order the switches with the Dell Modular Server Chassis, the switches are already installed, and no unpacking is required. The unpacking procedure applies only if you order a Cisco M SFS7000E InfiniBand Switch, separately or without a chassis.
Installing the Cisco M SFS7000E InfiniBand Switch
This section describes how to install the Cisco M SFS7000E InfiniBand Switch.
The Cisco M SFS7000E InfiniBand Switch can be hot-swapped while the Dell 10G system (PowerEdge) is online. When you install a switch, you do not need to power down the server chassis.
The Cisco M SFS7000E InfiniBand Switch fits into four different bays on the Dell Modular Server Chassis. These bays connect to either fabric B or C. Each one of these fabrics connects to a mezzanine card on each of the 16 server modules. The HCA is designed to reside in these mezzanine connectors. Two switches may be used for each fabric in a non-blocking configuration. Multiple fabrics may be used simultaneously for increased bandwidth.
Note Each bay into which a Cisco M SFS7000E InfiniBand Switch fits must contain either a switch or a blank input/output module (IOM). When you remove a switch, you must either replace it with an identical switch or a blank IOM within one minute of removal.
To install the Cisco M SFS7000E InfiniBand Switch in the Dell Modular Server Chassis, perform the following steps:
Step 1 Select a chassis I/O module bay in which to install the switch. (See Figure 3 for the location of the I/O module bays.)
If the HCA IB mezzanine card B is installed, you may install the Cisco M SFS7000E InfiniBand Switch in I/O slots B1 and/or B2. If the HCA IB mezzanine card C is installed, you may install the Cisco M SFS7000E InfiniBand Switch in I/O slots C1 and/or C2.
Figure 3 Chassis I/O Module Bays
Step 2 Remove the IOM blank from the selected bay, if it is present, and store it for future use.
Step 3 Remove the connector cover from the switch, and save it for future use. (See Figure 4.)
Figure 4 Removing the Connector Cover
Step 4 Press the release latch upward so the switch handle springs open and is perpendicular to the module. (See Figure 5.)
Figure 5 Switch Handle in Open Position
Step 5 Slide the switch completely into the selected bay until it stops, and then rotate the switch handle upward until it is secured by the release latch.
Figure 6 shows the switch being inserted into the server chassis and the direction in which to rotate the switch handle to secure it.
Figure 6 Inserting the Switch into the Server Chassis
Removing the Cisco M SFS7000E InfiniBand Switch
To remove the Cisco M SFS7000E InfiniBand Switch, perform the following steps:
Step 1 Disconnect any cables attached to the Cisco M SFS7000E InfiniBand Switch.
Step 2 Press the release latch upward so the switch handle springs open partially.
Step 3 Rotate the switch handle all the way down to eject the switch.
Step 4 Slide the switch out of the chassis bay.
Step 5 Install the I/O connector cover on the switch.
Note When you remove a switch, you must either replace it with an identical switch or a blank IOM within one minute of removal.
Connecting InfiniBand Cables
This section describes briefly how to connect your IB cables.
Use IB cables to connect your Cisco M SFS7000E InfiniBand Switch. To plug in an IB cable, push the connector into the interface. For the pull connector, push the latch until it is engaged after it is in the interface. An alternative method to plug in a pull connector IB cable is to push the latch first, and then insert the connector until you hear a click. (See Figure 7 and Figure 8.)
Figure 7 InfiniBand Cable with Pinch Connector
Figure 8 InfiniBand Cable with Pull Connector
Note If the free space around a given IB port is tight, verify that your IB cable connector engages completely. Wiggle the connector back and forth to be sure that both sides of the connector have locked firmly into place.
To remove a cable with a pinch connector, pinch both sides of the back of the connector, as shown in Figure 9, and pull the connector away from the port.
Figure 9 Removing Cable with a Pinch Connector
To remove a cable with a pull connector, grasp the connector with one hand and push it toward the port, and then pull the latch away from the port with your other hand while gently wiggling the connector away from the port, as shown in Figure 10.
Figure 10 Removing Cable with a Pull Connector
Note The Cisco M SFS7000E InfiniBand Switch also supports optical connections through external pluggable optical modules.
External LED Specifications
This section describes the external LED specifications for the Cisco M SFS7000E InfiniBand Switch.

InfiniBand Port Status LEDs
A port status LED indicator (green) exists next to each IB port on the Cisco M SFS7000E InfiniBand Switch, as shown in Figure 11. Table 2 describes IB port status LED indicators. The eight ports on the IB switch module are numbered next to each LED indicator.

Switch Status LEDs
Each IB switch module includes two LEDs (one green and one bi-color, blue and amber), as shown in Figure 11. The power LED and the system status LED provide the overall system status for the Cisco M SFS7000E InfiniBand Switch and are controlled by the Dell Remote Access Controller/Modular Chassis (DRAC/MC) management board. The DRAC/MC checks whether or not the switch blade is valid and has correct identifiers. Table 3 describes the green-colored power LED indicator. Table 4 describes the bi-colored system status LED indicator.
External Network Management Requirements
You can manage the Cisco M SFS7000E InfiniBand Switch in an InfiniBand network by using the Cisco High-Performance Subnet Manager or the Cisco Embedded Subnet Manager.
