2 Installation Facility Guidelines
This section provides guidelines for preparing the installation site for Integrity NonStop
NS-Series systems:
Modular Cabinet Power and I/O Cable Entry
Power and I/O cables can enter the Integrity NonStop NS-series server from either the
top or the bottom rear of the modular cabinets, depending on how the cabinets are
ordered from HP and the routing of the AC power feeds at the site. Integrity NonStop
NS-series server cabinets can be ordered with the PDU junction boxes installed either:
•
Top, rear: Power and I/O cables are routed from above the modular cabinet.
•
Bottom, rear: Power and I/O cables are routed from below the modular cabinet
Emergency Power-Off Switches
Emergency Power Off (EPO) switches are required by local codes or other applicable
regulations when computer equipment contains batteries capable of supplying more
than 750 volt-amperes (VA) for more that five minutes. Systems that have these
batteries also have internal EPO hardware for connection to a site EPO switch or relay.
In an emergency, activating the EPO switch or relay removes power from all electrical
equipment in the computer room (except that used for lighting and fire-related sensors
and alarms).
EPO Requirement for Integrity NonStop NS-Series Servers
Integrity NonStop NS-series servers without the optional HP 5500 XR UPS installed in
each modular cabinet do not contain batteries capable of supplying more than 750 volt-
amperes (VA) for more that five minutes, so they do not require connection to a site
EPO switch.
