·If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Statement 1006
This section describes how to install the Cisco SFS 7000P and SFS 7000D Server Switches in an equipment rack.
In addition to the accessories provided with the switch, you need the following:
•A number 2 Phillips screwdriver
•8 rack screws specific to your rack
•Any associated mounting clips to secure the brackets to your rack (two for each rail of the rack)
Installing the rack to the system with screws other than the ones recommended could be hazardous.
•A rack with enough clearance for the server switch cables
•Two people to perform the installation (highly recommended)
Note The Cisco SFS 7000P and SFS 7000D Server Switches weigh more than 22 pounds (10 kilograms) each.
Rack-Mounting the Switch
To mount the Cisco SFS 7000P and SFS 7000D Server Switches in a rack, follow these steps:
Step 1 Remove the switch, rack-mount brackets, contents of accessory kit, and documentation from the box.
Step 2 Place the switch on a secure, clean surface.
Step 3 Record the MAC address and the Globally Unique Identifier (GUID) number for future reference.
The MAC address and GUID number are available on sticker labels placed on top of the switch.
Step 4 Check the slot in the rack for sufficient clearance.
Step 5 Determine the desired method of installation, and follow the appropriate steps:
•Installing the Switch with One Person
•Installing the Switch with Two People
Installing the Switch with One Person
Because it can be difficult for one person to align the switch correctly along both rack rails, the following installation method is easier with two people but can be accomplished with one person.
To install the switch with one person, follow these steps:
Step 1 Separate one set of the rack brackets. (See Figure 3-1.)
Each side is assembled to its counterpart but should be separated before you attach them to the switch when you use this installation method.
Figure 3-1 Assembled Rack Brackets
Step 2 Attach the bracket that has the screw holes to the side of the switch, with the flange facing away from the switch, as shown in Figure 3-2.
Figure 3-2 Attaching One Rail to Switch Chassis
The standard method is to face the flange toward the front of the switch. However, you can also mount the flange toward the back if you want to mount the switch backward in the switch (service-side forward), as shown in Figure 3-2.
Step 3 Repeat Step 1 and Step 2 on the opposite side of the switch to attach the second bracket.
The two counterparts to these sliding rack brackets (that do not have screw holes) should still be unattached.
Step 4 Check the rack for clearance for the switch. The switch can be installed either directly on top of another device or be suspended from the rack posts.
Step 5 Attach the remaining two rack brackets to your rack.
a. Position a bracket toward the back of the rack with the flange facing away from the rack. The flange should go around the outside of the rack post, as shown in Figure 3-3.
Figure 3-3 Holding Bracket Inside of Rack
Note If you are rack-mounting the switch backward, the bracket should be installed to the front of the rack.
b. Secure the bracket with the screws through the back of the rack, as shown in Figure 3-4.
c. Repeat on the other side of the rack.
Figure 3-4 Secure Rail Bracket to Rack with Screws
Step 6 Lift the switch unit, and align the sliding brackets to the switch with the brackets attached to the posts before sliding them together.
Step 7 Carefully push the switch unit into the rack, as shown in Figure 3-5.
If the brackets do not slide easily, the alignment might be off. Pull the switch back toward you, and realign the brackets.
Figure 3-5 Sliding the Switch Into the Rack
Step 8 Maintain at least six inches between the cooling vents and any obstructions.
Step 9 Secure the switch with your screws through the front of the rack, as shown in Figure 3-6.
Figure 3-6 Secure Switch with Screws through the Front of the Rack
Installing the Switch with Two People
The following installation method requires two people to mount the switch into the rack. One person holds the switch while another person secures it to the rack.
To install the switch with two people, follow these steps:
Step 1 Separate the assembled rack brackets. (See Figure 3-1.)
Step 2 Attach the rack bracket that has screw holes to the sides of the switch by using the screws provided.
When attaching the rack bracket, the flanges of the rack bracket should be facing away from the switch. (See Figure 3-2.)
Step 3 Attach the rack brackets to their counterparts before inserting the switch into the rack.
Step 4 Insert the switch into the rack with the rack bracket attached. You must tilt the switch unit to one side to avoid hitting the sides of the rack bracket as they pass around the back rails.
Return the switch unit to a horizontal position after the switch is inside the rack. The rear bracket flanges should wrap around the outside of the back rack post. (See Figure 3-4.)
Step 5 Have one person hold the switch while another person secures the switch to the rack.
If required, adjust the length of the rack brackets to fit the dimensions of the rack posts.
Step 6 Maintain at least six inches between the cooling vents and any obstructions.
Step 7 Attach the rack bracket to the back of the rack posts with screws that fit your rack.
Step 8 Attach the front rails to the front of the rack with screws that fit your rack. (See Figure 3-6.)
Configuring Basic Connectivity
The following sections appear in this section:
•Obtaining an IP Address
•Connecting the 10/100 Ethernet Management Port
•Powering Up the Chassis
Obtaining an IP Address
Obtaining an IP Address from the DHCP Server for Ethernet Management
This section describes how to obtain an IP address from the Dynamic Host Configuration Protocol (DHCP) server by default.
Note DHCP is enabled by default in the Cisco SFS 7000D Server Switch. To obtain an IP address for the Cisco SFS 7000P Server Switch, see "Obtaining a Static IP Address for Ethernet Management" section.
To obtain an IP address using the default enabled DHCP, you must obtain the MAC address. The MAC address is printed on a label on your Cisco SFS 7000D Server Switch in the following format: AA:BB:CC:DD:EE.FF. (See the instructions in the "Rack-Mounting the Switch" section for when to make a note of the MAC address.) You must configure your DHCP server to the MAC address before you attempt to obtain an IP address using DHCP.
Use the MAC address to configure your DHCP server to allocate an IP address of your choice to the Cisco SFS 7000D Server Switch management interface. Otherwise, the DHCP server (if present) allocates the first available IP address from the designated pool of addresses. In the latter case you can find out which address was allocated by logging to the CLI on the serial console and using the show interface mgmt-eth command. See the Cisco SFS 7000 Series Product Family Command Reference for further details on using CLI commands.
Use the IP address, to Telnet to the Cisco SFS 7000D Server Switch.
Obtaining a Static IP Address for Ethernet Management
A Cisco SFS 7000P Server Switch user must configure a static IP Address for Ethernet Management. A Cisco SFS 7000D Server Switch user can configure a static IP address and connect to a serial console port only if a DHCP server is not available.
To configure a static IP address, you must connect the serial console port to a PC serial for access to the server switch.
Before you configure the switch, ensure that the unit is connected properly. This section describes how to attach a serial console cable to a PC. The serial console port, located on the rear panel of the
Cisco SFS 7000P and SFS 7000D Server Switches, is shown in Figure 3-7 and Figure 3-8.
Figure 3-7 Connecting the Console Cable to a Serial Console Port on the Cisco SFS 7000P Server Switch
Figure 3-8 Connecting the Console Cable to a Serial Console Port on the Cisco SFS 7000D Server Switch
You can connect the serial console port to a PC serial port for local administrative access to the switch. A terminal emulation software product, such as HyperTerminal, makes communication between your switch and your PC possible during setup and configuration.
To connect the console port to a PC, follow these steps:
Step 1 Configure the baud rate and character format of the PC terminal emulation program to match the following management port default characteristics:
•Baud: 9600 bps
•Data Bits: 8
•Stop Bits: 1
Step 2 Connect the supplied DB-9/RJ-45 female adapter or DB-25/RJ-45 female adapter (depending on your PC connection) to the PC serial port.
Step 3 Connect one end of the supplied console cable (a flat rollover RJ-45 cable) to the serial console port. (See Figure 3-7 and Figure 3-8.) Connect the other end to the DB-9/RJ-45 female adapter or DB-25/RJ-45 adapter at the PC serial port.
After you connect the serial console port, you may configure a static IP address for the Ethernet management interface by following these steps:
Step 1 Wait for the login prompt.
Step 2 Enter the username and password. The default username is super, and the default password is super.
Step 3 Enter the enable command.
Step 4 Enter the configure command to enter the configuration mode.
Step 5 Enter the interface mgmt-ethernet command to enter the config-if-mgmt-ethernet mode.
SFS-7000D(config)# interface mgmt-ethernet
Step 6 Enable the static address option, which turns off the default-enabled DHCP.
SFS-7000D(config)# address-option static
Step 7 Enter the IP address of the management interface, followed by the netmask, which enables the optional static address.
SFS-7000D(config-if-mgmt-ethernet)# ip address ip address netmask
Step 8 Set the default gateway for the management interface. See your system administrator for a gateway address.
SFS-7000D(config-if-mgmt-ethernet)# gateway ip address
Step 9 Enable the management interface by entering the no shutdown command.
SFS-7000D(config-if-mgmt-ethernet)# no shutdown
Step 10 Save the configuration to preserve it between reboots.
SFS-7000D# copy running-config startup-config
Connecting the 10/100 Ethernet Management Port
The autosensing 10/100 Ethernet management port is located on the rear panel/port connectors side of the Cisco SFS 7000P and SFS 7000D Server Switches. (See Figure 3-7 and Figure 3-8.) The Ethernet management port is used for out-of-band management of the Cisco SFS 7000P and SFS 7000D Server Switches.
Use the CAT-5 twisted pair RJ-45 straight-through cable to connect the 10/100 Ethernet management port to external hubs, switches, and routers.
Powering Up the Chassis
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034
When you power up the chassis, use only the power cable provided with your InfiniBand system.
To power up the chassis, follow these steps:
Step 1 Remove the power cords from the shipping package.
Two power cords are available: UL-rated, 10 amps and 125 VAC or greater.
Step 2 Inspect the power cord to determine if it provides the proper plug and is appropriately certified for use with your electrical system. Discard the cord if it is inappropriate for your national electrical system, and obtain the proper cord, as required by your national electrical codes or ordinances.
Grounding is supplied by the ground prong on the three-prong power plug. Do not attach a separate ground cable, and do not use adapter plugs. Do not remove the ground prong from the cable. Be sure that the ground connection on the power supply is correct and functioning before applying power to the switch.
Step 3 Connect the power cords to the power connectors on the rear of the switch.
The system automatically boots up. You can watch the operation status by using the serial console.
For power connector locations for the Cisco SFS 7000P Server Switch, see Figure 3-9. For power connector locations for the Cisco SFS 7000D Server Switch, see Figure 3-10.
Figure 3-9 Power Connector Locations for the Cisco SFS 7000P Server Switch
Figure 3-10 Power Connector Locations for the Cisco SFS 7000D Server Switch
Step 4 Connect the other end of each AC power cable into a 90-to 264-VAC power outlet operating between 47 Hz and 63 Hz.
The switch automatically starts and boots up. Use the correct external power source. Attach the switch only to approved power sources, as indicated by the electrical ratings label. If you are unsure of the correct power-source to use, contact your support personnel or your local power company.
Step 5 Check the LEDs on the front of the Server Switch.
When the device first powers up, it performs a POST. (See the "LEDs" section on page 5-1.)
Step 6 Log in and assign a network address after you see the login prompt.
The default login is: super, and the default password is: super.
For additional management information, see the Cisco SFS 7000 Series Product Family Command Reference.
Connecting Network Devices
This section describes how to connect the InfiniBand switches to other network devices. These InfiniBand switches can then be interconnected to InfiniBand devices such as InfiniBand-enabled servers.
The Cisco SFS 7000P and SFS 7000D Server Switches support the following types of connectors:
•Serial console port
•Ethernet Management port—RJ-45 jack for unshielded twisted-pair connections
•Cisco SFS 7000P Server Switch—4x 10-Gbps InfiniBand connectors
Cisco SFS 7000D Server Switch—4x 10/20-Gbps InfiniBand connectors
Note There is a performance degradation if you mix 10-Gbps and 20-Gbps InfiniBand ports.
Connecting InfiniBand Devices
Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not view directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard. Statement 1056
To use InfiniBand to connect to other workstations or switches, you need standard 4x InfiniBand cables. InfiniBand cables can be used to connect any two InfiniBand devices, whether a switch or a host. (Figure 3-11 and Figure 3-12 show InfiniBand ports on the Cisco SFS 7000P and SFS 7000D Server Switches.) For more information about InfiniBand cables, see the InfiniBand SDR, DDR, and QDR Technology Overview.
Note Copper passive DDR cables are limited to 8 meters in length. If you want to use a longer SDR cable in place of a DDR cable, the port must be comfigured manually to run an SDR rate.
Figure 3-11 Port Connections for the Cisco SFS 7000P Server Switch
Figure 3-12 Port Connections for the Cisco SFS 7000D Server Switch
To connect InfiniBand devices, follow these steps:
Step 1 Connect InfiniBand cables from the host to the InfiniBand switch.
a. To connect an InfiniBand cable, push the connector into the interface until you hear or feel a click. Figure 3-13 shows an InfiniBand cable with a pinch connector, and Figure 3-14 shows an InfiniBand cable with a pull connector.
Figure 3-13 InfiniBand Cable with Pinch Connector
Figure 3-14 InfiniBand Cable with Pull Connector
Note If your host does not provide an ample amount of space around an InfiniBand port, double-check that your InfiniBand cable connector engages fully. Move your connector back and forth to be sure that both sides of the connector have locked firmly into place.
b. To remove a cable with a pinch connector, pinch both sides of the back of the connector and pull the connector away from the port. (See Figure 3-15.)
Figure 3-15 Removing a Pinch Connector
c. To remove a cable with a pull connector, grasp the connector with one hand and push it toward the port, then pull the latch away from the port with your other hand and gently move the connector back and forth and away from the port. (See Figure 3-16.)
Figure 3-16 Removing a Pull Connector
Connecting Ethernet Management Devices
To connect the Ethernet management port to external devices such as switches, routers, and hubs, use an Ethernet cable. For the location of the Ethernet management port, see Figure 3-11 and Figure 3-12.
Managing the System
You can manage the InfiniBand system using the following methods:
•Command-Line Interface (CLI)—A text-based interface accessible through a direct serial connection, Telnet over IP, or SSH over IP
•Chassis Manager (GUI)—A web-based graphical user interface
•Element Manager (GUI)—A graphical interface installed on a workstation, accessible over IP
See the Cisco SFS 7000 Series Product Family Command Reference, Cisco SFS 7000 Series Product Family Chassis Manager User Guide, and the Cisco SFS 7000 Series Product Family Element Manager User Guide for more information about managing InfiniBand systems.
