Blade Enclosure Inter Connect
If more than one Blade Enclosure (SIGMABLADE-Hv2) are mounted in a single rack, connecting the
UPPER port, a connector on the rear face of a Blade Enclosure, to the LOWER port, a connector on the
rear face of the Blade Enclosure just above, and the LOWER port, another connector on the rear face,
to the UPPWER port, a connector on the rear face of the Blade Enclosure just below, through LAN
cables (straight) allows the EM cards to share the rack name and its unique ID among the connected
blade enclosures.
The EM cards can read the status information of the Blade Enclosures and display the information on
Web consoles.
The Rack Information screen on a Web console has the link of each connected Blade Enclosure to the
Web console.
When the same user name and password are set for all the Web consoles, you can automatically log in
to any Web console through the link to the Web console.
See Chapter 4 for details of the Web console.
IMPORTANT:
 For the Blade Enclosure inter connect, use LAN cables (straight) as short as possible. LAN
cables of three meter or less are recommended.
 Do not connect a LAN cable to the UPPER port of the Blade enclosure at the top in a rack and
the LOWER port of the Blade Enclosure at the bottom.
CHECK:
Check that LAN cables are connected above and below appropriately. Each of the EM cards
recognizes the positional relationship among the Blade Enclosures in the rack depending on the cable
connections to the UPPER and LOWER ports on the Blade Enclosures. Some incorrect cable
connection disables the EM cards to recognize the positional relationship among the Blade Enclosures
properly.
TIPS:
Up to six Blade Enclosures can be subject to the Blade Enclosure inter connect.
