ESM bays: Your expansion unit comes with
two hot-swappable ESM boards. The
environmental services monitor (ESM)
boards provide a 1 gigabit FC interface to
the drives and monitors the overall status of
the expansion unit. Each ESM board has
two GBIC connector ports for connecting
your expansion unit to the controller or
connecting two or more Netfinity FAStT
EXP500 expansion units together. The ESM
boards provide redundancy when both
boards are configured into redundant FC
loops. Refer to your FC controller
documentation to determine if the controller
supports this redundancy function.
Hot-swap fan bays: Your expansion unit
has two interchangeable hot-swap and
redundant fan units. Each unit contains two
fans. If one fan unit fails, the second fan
unit continues to operate. Both fan units
must be installed to maintain proper cooling
within your expansion unit, even if one fan
unit is not operational.
Hot-swap power supply bays: Your
expansion unit comes with two hot-swap and
redundant power supplies. Both power
supplies must be installed to maintain proper
cooling within your expansion unit, even if
one power supply is not operational.
