Cabling the Enclosure
CAUTION:
Do not connect external devices to the enclosure link (RJ-45) connectors unless the device
is listed as a supported device on the Quickspecs. Connecting an unsupported external device to the
enclosure link (RJ-45) connectors may damage your external device or the PC Blade Switch itself.
To cable a HP PC Blade Enclosure already installed in a rack:
1.
For accessing and configuring the Integrated Administrator locally, connect a client device (running
VT-100 terminal emulation software) to the Integrated Administrator console connector using a
null-modem cable. For accessing and configuring the Integrated Administrator over your network,
connect the Integrated Administrator to your management network via the management connector.
NOTE:
By default, ports 42, 45, and 46 are assigned to the same internal VLAN, so take this into
consideration when planning for Spanning Tree loop avoidance.
2.
Connect the PC Blade Switch to your network.
●
For the interconnect switch, only NIC A on each blade PC supports PXE. So, use either port
45 or 46 to connect to your image management network. By default, the Integrated
Administrator (port 41) and its external port (42), are members of the image management
VLAN (VID 1). If you connect port 42 in addition to either port 45 or 46 to the same network
segment, Spanning Tree will block the higher ports, potentially leaving you with degraded
performance. To address this, start by determining if it is acceptable to access the Integrated
Administrator from the image management network. If so, there is no need to connect port
42. If you have a dedicated administrative network separate from your image management
network, consider placing port 41 and 42 into their own VLAN, for example, VID 3. If ports 41
and 42 are put into VLAN 3, the switch can also be managed out-of-band by giving VLAN 3
an IP address of its own. Be sure to disable DHCP on VLAN 1 and 2 and, if routing IP for
remote management, be sure to assign a global IP default gateway address.
3.
Connect the AC power cord (provided) to each hot-plug power supply.
CAUTION:
The enclosure will power up as soon as an AC power cord is connected to a power
source and a power supply.
