General Notes
1. It is recommended that the 0v/chassis connections are all connected together externally.
2. Allow 1RU above and below the unit for ventilation.
3. Do not exceed the maximum PSU-22 rating of 240W. This rating takes into account the internal
temperature rise limitations and is a safe maximum rating. Each RJ45 connector can supply up
to about 1.1A at +24V. This is to allow products such as the ML1 (which draws approx 800mA)
to be powered along with a combination of the standard displays up to a maximum of 240W.
4. For RJ 45 connected TSL equipment, the pin-out is 1:1.
5. The RJ 45 connectors must only be used to connect TSL UMD equipment together.
6. It is recommended that Category 5E FTP (foil screened twisted pair) cable is used. The
individual cores are rated at 1A at 24volts. Two cores are use for each power rail.
7. Each RJ45 output connector is individually buffered for both power and data from the others.
