2.5 Communication / Interface Options
The CFR is equipped with four rear panel jacks for communication and remote
interfaces: RS-232 Serial data; LAN Interface; External IID and External Alarms.
Units with the external modem option have a fifth connector for modem connection.
NOTE: With the SID installed in the UPS, either the External IID port or
the RS-232 port can be activated. The factory default is set for RS-232
operation. With the internal IID option installed in the UPS
both ports are
active.
RS-232 Monitoring / Control Applications
The Alpha CFR-UPS provides a standard RS-232 serial port on a DE-9 female
connector. This port may be used to monitor and control the CFR using 1) ASCII
terminals, 2) UPS monitoring software and 3) SNMP agent devices.
You may use the serial port to interface with a dumb terminal or a personal
computer (running a terminal emulation software) to monitor, control, and calibrate
the CFR. All you need is a standard off-the-shelf RS-232 cable (straight through)
and a terminal. Refer to section 5 “RS-232 TERMINAL COMMUNICATION” for
more information.
You may also use the RS-232 serial port to communicate with the intelligent
UPS monitoring software running on a host computer or a SNMP agent device
connected to your LAN network. Alpha Technologies provides the “AlphaNet C”
family of UPS monitoring software and SNMP agents to manage your network
requirements. You can use the “AlphaNet C shutdown software” to monitor the
CFR in a network environment and to perform an orderly system shutdown when
the battery becomes low (during extended line fail situations). AlphaNet C
shutdown software informs all workstations of pending power failures and
shutdowns and in multi-server networks, AlphaNet can shutdown other servers in
the network as well as the workstations. For a full description of the features and
capabilities of AlphaNet C shutdown software, refer to its user’s manual or contact
Alpha Technologies. AlphaNet C is available for all major network platforms and
operating systems — Novell Netware, SCO Unix, IBM OS/2, IBM AIX, Sun Solaris,
Hewlett-Packard HP-UX (DAT), and Digital Equipment (OS/F, VMS, and DECNET).
Alpha Technologies also provides the “AlphaNet CS SNMP Agent Device” to
monitor and control the CFR using the SNMP protocol. This provides an interface
between the CFR and your network environment and allows you to use your
Network Management Station (NMS) to monitor and control the CFR. To obtain
detailed information on SNMP management solutions for your CFR refer to
AlphaNet CS SNMP Agent User’s Manual or contact Alpha Technologies.
CAUTION: INTERNAL MAINTENANCE SHOULD BE SERVICED ONLY BY
QUALIFIED PERSONNEL.
1. Disconnect all loads from the OUTPUT receptacles on the UPS.
2. Switch the rear panel BATTERY circuit breaker OFF.
3. Disconnect the UPS from the AC wall receptacle.
4. If an external battery pack is connected to the UPS, remove the connector
from the UPS rear panel.
5. Loosen the two (2) Phillips screws from the UPS front panel (located in the
lower grill). Carefully pull the lower part of the front panel away from the UPS
and lift the panel straight up.
6. Remove the twelve (12) Phillips screws from the sides and rear of the UPS.
7. Carefully lift the cover upward until it clears the chassis.
