Quad Loop
Configuration Note: Quad loop configuration requires that the enclosure be
configured in split loop mode. To set split l oop mo de, a j umpe r
must be installed at jumper location JP3 on each LS module
in the enclosure.
This section describes the procedure for connecting the
enclosure in quad loop mode. For this configuration there
must be two LS modules and two I/O modules installed in
the enclosure.
1Remove both LS modules from the enclosure and install a
jumper, at jumper location JP3 if one is not already installed.
This sets the enclosure to operate in split loop mode.
2Attach cables to the top and bottom connector of both I/O
modules (see Figure 3-4).
3Attach the other end of these four cables to your host systems.

CAUTION: Enclosures in split loop mode can not be daisy
chained to other enclosures.
