HP BladeSystem c3000 Tower Enclosure Setup and Installation Guide

Cabling and powering up the enclosure 45
Item Connector Description
1 Enclosure link-
down port
Connects to the enclosure link-up port on the enclosure beneath it using a CAT5
patch cable.
2 Enclosure link-up
port and service
port
Connects to the enclosure link-down port on the enclosure above it using CAT5
patch cable. On a stand-alone enclosure or the top enclosure in a series of linked
enclosures, the top enclosure link-up port may function as a service port.
3 OA1/iLO Onboard Administrator Ethernet connection. Use a CAT5 patch cable to connect to
the management network. Connect to this port to remotely communicate with the
Onboard Administrator, all iLO ports on each blade, and supporting interconnect
module management parts.
4 OA2/iLO Reserved for future Onboard Administrator connections.
NOTE: If the Onboard Administrator is connected to a network with a DHCP server when you
power up the enclosure, the Onboard Administrator and each iLO (one for each blade)
consumes a DHCP lease.
Cabling a PC to the enclosure service port
You can temporarily connect a PC to the enclosure to access the Onboard Administrator modules, iLO 2,
and interconnect modules with Ethernet management ability.
1. On the enclosure you are logging in to, use the Insight Display to obtain the Service IP address of
that active Onboard Administrator module on the Enclosure Info screen. The Service IP address can
be found in the Enclosure Settings ("Enclosure Settings screen" on page 55) screen.
2. Connect the laptop or PC 10/100Mb Ethernet port configured for DHCP addressing to the available
link-up port on the enclosure using a standard CAT5 patch cable. A Microsoft® Windows® PC
automatically obtains an IP address. If no IP address is obtained, configure the PC Ethernet port for
static addressing using the IP address 169.254.1.254 with a netmask of 255.255.0.0.
3. Open a web browser on the PC, and then enter the active Onboard Administrator module Service IP
address found in the Enclosure Info screen in step 2.
4. Log into the Remote Onboard Administrator. For information on using the Remote Onboard
Administrator feature, see the HP BladeSystem Onboard Administrator User Guide.
Cabling the network to the enclosure
Cable the interconnect modules to the enclosure. See "Mapping to interconnect ports (on page 34)" and
the supporting documentation that came with your interconnect modules for specific details on cabling the
interconnect modules.
Installing a PDU
The PDU can be installed in either a 1U or a 0U configuration. For specific details on installing the PDU
into the enclosure, see the installation instructions that ships with the PDU.
